Sniffles

Sniffles is a structural variation caller using third generation sequencing (PacBio or Oxford Nanopore). It detects all types of SVs (10bp+) using evidence from split-read alignments, high-mismatch regions, and coverage analysis. Please note the current version of Sniffles requires sorted output from BWA-MEM (use -M and -x parameter), Minimap2 (sam file with Cigar & MD string) or NGMLR.

How to build Sniffles

wget https://github.com/fritzsedlazeck/Sniffles/archive/master.tar.gz -O Sniffles.tar.gz
tar xzvf Sniffles.tar.gz
cd Sniffles-master/
mkdir -p build/
cd build/
cmake ..
make

cd ../bin/sniffles*
./sniffles

Note Mac users often have to provide parameters to the cmake command:

cmake -D CMAKE_C_COMPILER=/opt/local/bin/gcc-mp-4.7 -D CMAKE_CXX_COMPILER=/opt/local/bin/g++-mp-4.7 .. 

NGMLR

Sniffles performs best with the mappings of NGMLR our novel long read mapping method. Please see: https://github.com/philres/ngmlr
