as a disk image.Note: For Mountain Lion (OS X 10.8), Mavericks (OS X 10.9), Yosemite (OS X 10.10) and El
Capitan (OS X 10.11) users: this External Web Page describes how to enable installation of
applications from sources other than the Mac App Store.
§ Un-package.
· Before any software can be installed, it must first be un-packaged. A disk image
can be thought of as the virtual equivalent of a CD.
The Alamut® Genova application in the disk image is contained within a single
file: for instance "AlamutGenova-2.11.0.dmg"You then "insert" or "mount" the disk image into the machine by double-clickingthe file. Having done this, the disk image will appear as another device in theFinder.
§ Installation.
· The final step of the process is to actually install the software where you
have read-write permission. An application bundle to install Alamut® Genova is
provided.All you have to do is copy the program to your desired location (usually yourApplications folder) and run it. Copying the program is performed simply byusing drag and drop.
§ Post Installation.
· After you have finished installing the program you should remove the files used
for the installation. You should unmount the disk image that was used in theinstallation process. This can be done by using the eject icon next to it in theFinder sidebar. You can also drag the mounted disk icon to the Trash.
· Set up Alamut® Genova with your credentials:
o Inside the folder where Alamut® Genova has been installed, find
the AlamutGenova file, and double-click on it to launch the program.Note: For Linux users, double-click on the file AlamutGenova.sh to launch the program.
o Accept the End User License Agreement.

8.2.3.4 Background on Prediction Methods
· SpliceSiteFinder-like is a method based on position weight matrices computed from
a set of human constitutive exon/intron junctions for donor (both GT and GC) andacceptor sites.
· Alamut® Genova uses the matrix described by Zhang et al. (1998) for branch points
and the algorithms described in Shapiro et al. (1987).
· MaxEntScan is a method based on the Maximum Entropy principle, developed by the
Burge Lab at MIT and described in Yeo et al. (2004). The MaxEntScan splice site
datasets and algorithms are fully integrated inside Alamut® Genova, with permission
84
55
Alamut Genova User Manual (EN) Version 1.4 © 2018 Interactive Biosoftware, a SOPHiA GENETICS Company

from Christopher Burge. Alamut® Genova only reports scores from the Maximum
Entropy Model.
· NNSPLICE (available at the Berkeley Drosophila Genome Project website is a
prediction method based on neutral networks (Reese et al. 1997). Although not fullyintegrated inside Alamut® Genova, it is transparently queried from within the software.Alamut® Genova reports scored from NNSPLICE 0.9.
· GeneSplicer, an ‘Open Source’ software available from the University of Maryland
CBCB, combines several splice site techniques; among them Markov models (Pertea
et al.2001). Known Constitutive Signals Alamut® Genova reports in the splicing
module each occurrence of the 9-mers (3 exonic + 6 intronic nucleotides) found in thedonor subset of human constitutive exon/itron junctions, and each occurrence of the 6-mers (4 intronic + 2 exonic) found in the acceptor subset.
· Mercer et al. High confidence branchpoints uses exoribonuclease digestion and
targeted RNA-sequencing to enrich for sequences that traverse the lariat junction and
by split and inverted alignment, Mercer et al. (2015) identified 59,359 high-confidencehuman branchpoints in >10,000 genes, thus providing a first map of splicingbranchpoints in the human genome.
· Limnos: Alamut® Genova has added a new splicing predictor called Limnos. Limnos
predicts branchpoints by using logistic regression.
· ESEFinder uses a method that computes putative binding sites for Exonic Splicing
Enhancers (Cartegeni et al. 2003). We have embedded these ESEFinder matrices
(licenced from Cold Spring Harbor Laboratory) inside Alamut® Genova so as to
perform the same computation as that provides by the CSHL ESEFinder website
· In the RESCUE-ESE approach, specific hexanucleotide sequences are identified as
candidate ESEs (Fairbrother et al., 2002). The set of human hexamers available fromthe RESCUE-ESE website are embedded inside Alamut® Genova.
· EX-SKIP compares the ESE/ESS profile of a wild-type and a mutated allele to quickly
determine, which exonic variant has the highest chance to skip this exon. It calculatesthe total number of ESSs, ESEs and their ratio. It computes specifically the number of
RESCUE-ESEs (Fairbrother et al. 2004; Fairbrother et al.,2002) FAS-ESSs (Wang
et al., 2004), PESEs/PESSs (Zhang et al., 2004), neighbourhood inference (Stadler
et al. 2006) and EIE/IIEs (Zhang et al., 2008) for each segment.
· The EX-SKIP tool is available through Alamut® Genova’s ESE Predictions Tab.

8.2.3.4.1 Set of Human Constitutive Exon/Intron Junctions
· We have gathered a set of human constitutive exon/intron junction sequences as
follows: From the RefSeq database (as of Dec. 2007) and with a reviewed status,10,728 human mRNA sequences were mapped onto the human reference genome(NCBI 36). Based on this mapping, genomic exon/intron boundary sequences wereextracted into separate subsets for donor and acceptor sites.
· With these sequences, we have built three position weight matrices: two matrices for
donor sites (GT and GC sites), and one matrix for acceptor sites (AG sites).http://biodev.hgen.pitt.edu/cgi-bin/enologos/enologos.cgi .56

Programatic Access
14 Programatic Access
Alamut® Genova allows Extended Programmatic access, in a similar way to Almaut®
Visual, further allowing convenient access to gene information.
To use this feature, first check that the external software tool you are using enables such
communication with Alamut® Genova. Second, in the Options dialog box (menu
'Application' > 'Settings' > 'Network' tab), possibly change the port according to the
external software specifications. Then restart Alamut® Genova.
14.1 Programmatic Access For Software Providers
Alamut® Genova embeds a small local HTTP server. This server listens to local HTTP
GET and POST requests coming through the port that is specified in the Options dialogbox. The default port is set to 10000 but it can be changed to any available port, (thisrequires the user to set the appropriate port in the Alamut® Genova Settings dialogbox).
Two types of HTTP requests are processed by Alamut® Genova:· http://localhost:10000/version
Upon receiving this request, useful for testing purposes, Alamut® Genova outputs its
current version as plain text.· http://localhost:10000/show?request=MLH1:c.464T>G
This request asks Alamut® Genova to display any data available in the system (herevariant "MLH1:c.464T>G").
Any request that can be processed by the Go to: input field of Alamut® Genova can be
sent out with the "show" verb.
· Example in Java Script
The following examples can be embeded in a web page (for different reasons theymight not work with all web browsers).
For this to work Alamut® Genova must be running and with port set to 10000 in theOptions dialog box.
Example script for the GET 'version' request:
