3. USING PEIVIEW3.1. OPEN DATA FILE

Once the program started and went through a splash screen the operator should select a

data file to be examined or converted.

For easier selection there is possibility to use filter in open file dialog:

Clickhere


8/22/2019 Pei View

6/38


Once the file is selected, click on Open and the data file will loaded and data statistics will

be calculated. When the data is loaded from a selected file, different drop windows are shown

to select different types of data. Colored area of the display is used for graphic data

presentation.

There is an option to view file header (ASCII part of the source file) with menu item File

Header that is under menu File.

3.2. CHANNEL DATA SELECTION3.2.1. Numerical channel

Select channel drop

window (Channel selector)

allows the user to select

any recorded numerical

channel. Selected datachannel is presented in

graphic form in the upper

part of the colored part of

the display. If the data is a

multiple reading per

second type graph displays

the first reading for each

second. If the data is a

spectrum type then sum of

all readings in the second

is displayed, since thegraph is designed to

display 300 seconds of

continuous data.

To see individual samples within one second, place the mouse on any point of the graph

and internal samples will be shown in the lower part of the colored area. To observe the data

over the entire file use

the scroll bar on the

bottom part of the

colored area.

Statistics of the

data file (start, end, and

current record number)

are displayed on the left

hand side of the display.

Selected channel

information is also

displayed (min, max

and current value). Data

graph scale can be

adjusted for proper

viewing.

3.2.2. ASCII Data ChannelThe Select ASCII drop window (the most upper window on the form) allows selecting

any data that was recorded in ASCII format (ex. Line channel). This data is displayed in the

frame above the graph area.

Any changes of the ASCII data are shown when moving mouse over the data graph or bymoving the scroll bar.

3.2.3. Spectral channelSpectral data can be selected on the Select spectra drop window (the lowest window). This

data will be presented on the lower part of the colored area as one-second spectra, where the

amplitude is indicated

by color.

Again to see real

amplitude spectrum

place the mouse on the

sample and it will be

shown in the upper partof this area with the

automatic scale

displayed in red on the

top of the screen

(Spectrum scale).

Instant values of

the graph pointed to by

mouse are shown on the

left middle side of the

screen.

When the same

spectral channels are

selected in Select

channel and Selectspectrum drop

windows, the upper

graph represents a sum

of data between the blue

and red indicators.

Position of the indicators

can be adjusted.

Therefore a new data

window can be generated

from the spectral data.

A new spectral window generation is shown below. When upper or lower limit for the

spectra is changed new graph is generated. In each point it shows sum for the spectral window

that set by upper and lower limit. This newly generated channel can be stored in PEI binary

data format by selecting Save Spectra Segment option in the File menu.

New data channel

Upper limit

Lower limit

If file contains such spectral channel that is recorded twice per second it can be watched

in two steps: readings for the first half of a second and readings for the second half of a

second. Radio buttons are used to switch between graphs. It is also possible to have Sum ofthese graphs.

3.3. DATA EXPORTTo export data into ASCII format or Geosoft format use menu Data Export.

3.3.1. Export into geosoft GBN formatFirst step is to select channels for output file from the table of recorded channels.

Using Selection type Dialog it is possible to choose data selection type: by record

range or by lines, and target directory.


8/22/2019 Pei View

12/38


When Selection by record range is chosen Dialog for Record range trimming will

appear:

If source file has Record channel and its data is accurate selection by record number is

requested otherwise selection by scan number is requested.

When Selection by lines is chosen List with available lines will appear:


8/22/2019 Pei View

13/38


There is a possibility to change line number when exporting.

After lines selection confirmation dialog will appear and if

Yes is pressed all chosen lines will be listed to change.

Menu item Group Geosoft Output is used to

export a group of data files to Geosoft format. It is enabled

when no data files are open. Window Group Geosoft Output is used to select a group of files to

export. Use Ctrl or Shift key to select more than one file.

Proceed with selecting

channels and target

directory.


8/22/2019 Pei View

14/38


All files in a group suppose to have the same data channels. In case if some channels

are not found in an input file the warning will appear.

If any files in a group have invalid structure they will not be processed. All valid data files will

be exported.

NOTE: If a spectral channel that is recorded twice per second is exported to Geosoft or ASCII

format two columns will be generated for this channel: readings for the first half of a secondand readings for the second half of a second.

3.3.2. Export into ASCII formatASCII format export is similar to Geosoft format export but simpler. After all necessary

channels are selected dialog for output record range will appear. Record range can be selected

by record number. If Record channel data is not accurate selection is made by scan number

(scan number starts from 1). If export is successful .txt file will be created.

3.3.3. Spectrum ExportThere is provision for spectrum ASCII export with some options. Click on Spectrum

Output item in the Data Export menu:

Spectrum ASCII output dialog will appear:


8/22/2019 Pei View

15/38


The user can select any recorded

spectrum in spectrum combo box. The

spectrum can be exported as it is or converted

to other spectrum resolution using

Conversion radio buttons. For example 512-

channel spectrum can be converted to

resolution of 256 or 128 channels. Spin

buttons From and To in Channels box are used to select spectra channels to be exported.

Record range can be selected using From and To spin buttons in Records box.

Accumulate check box is used to accumulate selected record range into one record. CheckInclude Record Number check box to have record number in output file. Click on the icon in

Export to saving control to specify the output file name. When all settings are completed the

Output dialog will be similar to the following:

In This example ISP1D spectrum

channels from 65 to 150 will be exported intoASCII file Sp1.txt without conversion.

Selected record range is from 120 to 1560;

record number will be included into output

file.

Click OK. The final message will come

up:

Spectrum selection

3.4. MAGNETIC COMPENSATIONPEIView allows performing magnetic compensation. File with set of coefficients have

to be ready, its extension is .cor. To execute magnetic compensation choose Magnetic

compensation item in the Tools menu. It is enabled when binary data file is opened.


8/22/2019 Pei View

16/38


After menu Magnetic Compensation is clicked, list with available channels will appear. User

should select raw magnetometer data channels for compensation. Note that the number of

selected channels has to match with the number of sensors in coefficients file.

If OK button is clicked dialog will come out:

User has to select coefficients file and all required channels. X coordinate and Y coordinate are

used to calculate heading for each data point to pick up then appropriate set of coefficients.

Three fluxgate channels and altitude channel have to be selected. Altitude channel is not used in

calculation but it is reserved for possible future use. The user can pick up any channel in Altitude

combo box (ex. RECS channel). If all channels selected properly press OK button and, after

compensation is finished, message will appear:


8/22/2019 Pei View

17/38


Compensated file has the same name as source data file plus prefix C_. It contains additional

channels that are compensated magnetometer data channels. First letter in channel name is

changed to P. For example, if two raw data channels were compensated: RMg1, RMg2 then

compensated file will contain two additional channels: PMg1, PMg2. If open created file it is

possible to compare corresponding channels:

Red graph RMg1: raw

magnetometer data channel;

Blue graph PMg1:

compensated data channel.

If there is several source data files that have the same channel structure and can be compensated

using the same coefficients file it is possible to apply group magnetic compensation. This menu

item is enabled if no file is opened.

After Group Magnetic Compensation menu item is clicked Open Dialog box will appear where

user can select group of files (with Shift or Ctrl key):


8/22/2019 Pei View

18/38


After files are chosen user have to select channels to compensate from the same list as it

was in case of magnetic compensation for one file. And then select coefficients file and all

necessary channels. If all settings are correct, after compensation was completed message will

come out:

Note that all files selected for group magnetic compensation must have the same channel

structure, otherwise compensated data will be incorrect or error message will appear:

3.5. DATA CORRECTIONIt is possible to have simple data correction when one second data wasnt accurate or it was

lost. For example GPS data might be lost or spectrometer data might be received 0.4 second late

and the next second 0.4 second earlier. Sometimes it may happen and simple data correction may

help.

3.5.1. Record channel correctionTo make correction open file in which wrong data was found. Go to menu Correction and

choose item Check Record numbers. This is first step that must be made for data correction.


8/22/2019 Pei View

19/38


If Record channel data is not accurate message will come up:

If OK is pressed Record channel data will be

corrected and whole file with corrected Record channel

will be saved into new file that has name similar to

source file name but is extended with _C00:

In case if Record channel is correct the

following message will appear:

3.5.2. Selecting channels and records for correctionAfter Record channel is checked and corrected if necessary next step is to select channels.

Click menu item Select channels that is under menu Correction. Dual list with available

channels on the left side will appear. Choose

channels that have wrong data at the same second

and press OK. For example, on the following

picture all GPS channels have wrong data in 3173

record.


8/22/2019 Pei View

20/38


When channels for correction are selected it is necessary to select records where selected data

have to be corrected. Record selection is made by double clicking on the graph image on the main

form in an appropriate spot. When graph image is clicked dialog box will appear. Chosen record

number is shown in a spin window; related value of a selected on the main form channel is also

displayed. It is possible to increase or decrease record

number by pressing corresponding arrow in a spinwindow, current value will be displayed according to

record number.

This dialog box is also used to select values that

will be applied for correction of selected channels.

Values from the next record or from the previous

record might be taken for correction; average value

between next and previous record can be also

calculated. Press OK when all selections in dialog box

are correct.

If other records for currently selected channels need to be corrected double click on the graphimage again. Values for correction (next, previous or average) must be the same for all chosen

record numbers.

Note: There is no possibility to correct the first record and the very last record of the file. Use

Save Data File Copy instead.

3.5.3. Saving corrected fileIf channels and record numbers are chosen click on menu item Save copy with

correction. Corrected copy will be saved into file that has name similar to source file name but

extended with _C0A; final message will appear:

If this newly saved file needs further correction it has to be opened and procedures 3.5.2 and

3.5.3 have to be repeated. Names for consecutive corrected files will be created as following:

OldName_C0A,

OldName_C0B,

OldName_C0C

File

extension remains the same.

3.6. EASTING AND NORTHING RECALCULATIONIf UTM projection was used for the survey and survey area crosses zone boundary it might

be useful to recalculate X and Y coordinates using another CM or using False CM. Recalculate

X, Y coordinates option creates two new channels: Xcalc, Ycalc and saves them into a new

file. Original file is not corrupted. When Recalculate X, Y coordinates is clicked:


8/22/2019 Pei View

21/38


Corresponding dialog will come up:

Select Latitude and Longitude channels and enter Central Meridian that will be used for

coordinates recalculation. Check False CM check box to enter False CM. Press OK button

when all fields are completed. Easting and Northing will be recalculated according to given CM

and saved into a new file:

Suffix _XY is added to the original file name.

3.7. DOSE RATE AND CONCENTRATION CALCULATIONThere is an option to calculate dose rate and concentration from the spectrum data. Open

file and select spectrum channel in the spectrum selector.

Click Calc Concentration and Dose item in the Tools menu. Stripping Ratios and

Sensitivities file has to be opened from the Open File dialog (see the description of this file in

Appendix B):

Spectrum selector

22/38


Dose rate channel and concentration for Thorium, Potassium, and Uranium will be

calculated as new channels DoseR (nGyph), ctTh (pct), ctU (ppm), ctK (ppm). They will be

saved into a new file along with all existing channels. New file name will be created by adding

_ct suffix to the original file name:

If Dose Rate and Concentration are calculated for an accumulated file which was recorded

by PGIS system, accumulation time will be retrieved from the file header and from the

Accumulation time channel Atm (if exists). Dose rate and Th, U, K concentrations will be

calculated and saved into a file. The format is average value per second.

3.7.1. Batch Concentration and DoseThe Batch Concentration and Dose option requires PEIView to have no open files. Click

on Batch concentration and Dose in the Tools menu.

Select files by holding down the Ctrl or Shift key in appeared Dose and Concentration

window:


8/22/2019 Pei View

23/38


Then select Stripping Ratios and Sensitivities file with .cal extension. AfterConcentration and Dose Rate are calculated for all selected files the final message will appear.

New files will be created in the same directory where original files are located; suffix _ct

will be added to the original file name.

3.8. STRIPPING RATIO AND WINDOW SENSITIVITIESCALCULATION

PEIView version 5.2.6 and higher has the provision

for calculating stripping ratios and window sensitivities.

HASP key is required to use this option. If a user tries to

run it without the HASP key inserted into USB slot the

error message will come up:

Do not open any file. Click Calc Stripping Ratios and Win Sensitivities in the Tools

menu


8/22/2019 Pei View

24/38


Select Files dialog will come up.

The user has to specify the files recorded on calibration

pads with known element concentration:

Background pad Potassium (K) pad Uranium (U) pad Thorium (Th) pad.

Pad parameters file also has to be specified. Usually it is

named STANDARD.DAT.

When all files are selected click OK.

Information dialog will show up:

Source Data box shows accumulated

time for each file and spectrum channel

recorded from down looking crystals found

in each file.

The user has to specify crystal type and

number of down looking crystals. This

information is needed to determine the

detector volume.

Output files are specified in Output

box. The user may change the names ifneeded.

Click OK button. After calculations are

completed the final message will come up:

Spec.cal file containing stripping ratios and window sensitivities is used for Dose Rate and

Concentration Calculation (see section 3.7). Report file out.dat contains source, intermediate

data and output data. Source data includes Concentrations of Transportable Pads, Geometric

correction factors, K, U, Th window counts for each pad. Output data includes Window

Sensitivities, Stripping Ratios and Background Count Rates. Report example is given in

Appendix A.

Scrolling is synchronized on both forms: main form and extra view.

If ASCII channel is selected on the main form its value is shown also in Extra View windowon the title bar (Line50 value for Line channel on the picture above).

There is an option that allows choosing which value to display for each graph. Click the right

button on required graph setup area and context menu will appear. The menu consists of two

groups of items. The first group determines the value that is going to be represented by the trace

point:

The first readingwithin a second;

Average value for asecond;

Maximum valuewithin a second;

Minimum valuewithin a second;

Sum of all thevalues in a second;

Extremal - linebetween min and

max values within

a second;

Distinction - value1 if sum of readings

for a second equal

sum of readings for the previous second ; value 0 otherwise;


8/22/2019 Pei View

28/38


The second group allows choosing between three options:

Normal presenting data as is; First DD presenting the first digital derivative of data; Fourth DD presenting the fourth digital derivative of data.First DD and Fourth DD functions are disabled for Distinction and Extremal modes.

By default Normal and First reading items are chosen for all graphs but spectra. Normaland Sum are default values for spectra.

Two more functions were added for representing data: Gradient and Vector.

Gradient is a difference between two channels data. These channels must have thesame sampling per second and units.

Vector is calculated for fluxgate channels.

When Gradient

menu item is clicked

dialog box will

appear to choose

channel to calculate

gradient. Only

appropriate channelswill be shown:

When channel is selected and OK button is pressed

gradient calculation will appear on the graph.

For vector calculation the first fluxgate channel have to

be chosen for the graph and then menu item Vector isclicked. This channel and the next two channels will be taken for vector calculation. If

inappropriate channel was chosen error message will appear:

If the Separate graphs checkbox is checked, positioning of the mouse pointer on the graph

sample produces display of all the data within this second. It is shown in the lower part of the


8/22/2019 Pei View

29/38


graph area for three upper graphs and in the higher part for two lower graphs. This image does

not appear for Distinction and Extremal modes.

If a graph displays spectral channel that is recorded twice per second pop up menu is used to

switch between readings for the first half of a second, readings for the second half of a second

and their Sum.


8/22/2019 Pei View

30/38


To close Extra View window use the Close button on upper right corner of this window or

uncheck Extra View checkbox on the main form. All the information about graphs is saved. If

Extra View is reopened within working with the same data file, all the saved graphs will be

displayed. They will also be displayed if another data file from the same folder is opened. This

file is supposed to have the same data structure.

After application is closed all setups for main form and for Extra View window is saved. Ifdata file from the same folder is opened in the next session all graphs will be displayed.

3.10. DATA FILE COPYUsing menu item Save Data File Copy user can save copy of the source file. When this

option is chosen first step is to select channels for file copy. All channels or part of them may

be selected. Selection is made

from dual list that comes out:

Next is to choose target directory and record

range for output file. The following dialog is used

for this purpose:

In case if Record channel data is not

accurate this dialog will display scan number

instead of record number.

Output file extention will be .cpy, file

name will be generated as: OldFileName + _ + OldFileExtention. When copy is savedmessage will appear:


8/22/2019 Pei View

31/38


3.11. JOINING BINARY FILESBinary files that have the same channel structure can be joined into one file. If during a

survey several consecutive files were recorded joining might be useful to view for example full

survey path. To join files use menu item Join Binary Files:

Select files to join in Open File dialog box. To select multiple files use Shift or Ctrl key.

By default selected files will be arranged by file names (PEI binary file names include timewhen file was created). The user can choose the other order: by record numbers. To change the

sorting order use menu item Options under menu Tools before joining files:

After files are joined message similar to following will come out:

Extension for the joined file is .P99;

name is the same as name for the first file in a

sequence.

The maximum number of files to join is 45.

3.12. ASCII IMPORTUser can import data file that has an ASCII format and create PEI binary data file using

ASCII Import menu option:

ASCII file to be

imported should have

colomn structure where

the first row consist of

column headers:


8/22/2019 Pei View

32/38


Note: It is neccessary that source ASCII file has Record Number column. It should have

one of the fillowing names: , or .

The following picture demonstrates example of a text file to be imported by PEIView. The

columns in this file contain data with different sampling rate: 1 for Alt column, 2 for LA, 5 for

XCol, YCol, 10 for RMg column. Note that the first row of each record has no asterisk.

If source file format is correct it will be transformed into binary file and message will come

out:

Newly created file can be opened and viewed

with PEIView program.

APPENDIX B: CALIBRATION FILE FORMAT

Calibration file is used for dose rate and Th, U, K concentration calculation. The

example of this file is shown below:

0.3773;Alpha0.5229;Beta

0.8945;Gamma

0.0546;A

0.0025;B

0.02;G

16.22;Ksens

1.34;Usens

0.7;Tsens

1.05;Volume

The first six coefficients are the stripping ratios.

Alpha, Beta, Gamma are ratios of counts in a lower energy window to those in a higher

energy window:

Alpha : Th into U Beta : Th into K Gamma : U into K

A, B, G are ratios of counts detected in a high energy window to those detected in a low

energy window (the reverse stripping ratios): A : U into Th B : K into Th G : K into U

Ksens, Usens, Tsens are the window sensitivities for infinite sources.

Volume is the volume of the detector.
