2. Helpful hints in the processing of experimental dataContinuous processing and evaluation of experimental data is highly needed2.1. Organization of work, type of data- Avoid this approach: This year I am experimenting and next year is for the evaluation of what I have obtained- Miscellaneous software is in every day useTypes od data:- Numerical data - raw data or data converted to the numerical form, may be obtained with certain tool (ruler) or equipment (spectrophotometer)- Graphical data - very important set of results, their quantification is highly needed- Structural data - analytical data, outcomes from sequencing machines, etc..
2.1. Organization of work, type of dataSoftware used in modern laboratory:- Software controlling machines - sometimes very complex (PCR cycler), the most important is the form of the output (table, text)- Specialized software - very important in the field of image analysis and processing of sequence data- General software - text and spreadsheet editors, graphical software, presentation software, mainly products of Microsoft at the Charles University- Open source software - very good tools, often problems with the compatibility- Online software - mainly in bioinformatics, but there is also other software available (e.g. graphical editors)2. Helpful hints in the processing of experimental data
2.1. Organization of work, type of dataWindows Explorer or similar software (Windows Commander) Protocols named according to date - the folder in format YYMMDD (081030). Must correspond to date in the laboratory book.Never modify folder with raw data - copying to the folder with other files accompanying the experiment.Back up data - external HDD or DVD or CD, online hard drivesDo not delay backuping!!!Experiment must be always finished with complete documentation, do not start others without finishing the previous.2.
