skif2 "Specific k-mers Identification"

SkIf2 is a comparative genomic tool that detect genomic regions (from SNPs to genomic islands) specifically associated to a group of organisms (defined by the user).
SkIf2 can be employed to extract a specific genomic region related to a trait of interest.
SkIf2 is a new implementation of SkIf (Specific k-mers Identification, https://sourcesup.renater.fr/wiki/skif/).
SkIf2 allows to obtain 100% identical results to SkIf much faster and using less RAM, then SkIf2 can be used on hundreds or thousands of genomes.
SkIf2 was developed in C++ and is a software tool relying on GATB-CORE library.(https://gatb.inria.fr/software/gatb-core/)

Installation

Dependencies : cmake 2.8+ should be already installed (mandatory).

git clone https://git.renater.fr/anonscm/git/skif2/skif2.git
cd skif2
mkdir build
cd build
cmake ..
make -j8

Using SkIf2

SkIf2 -inGroupFile inGroupGenomePathsFile.txt -outGroupFile outGroupGenomePathsFile.txt -k 15 -outputFile specificInGroupKmers.csv
