; ; User configuration options for Strelka somatic small-variant caller ; workflow: ; [user] ; ; isSkipDepthFilters should be set to 1 to skip depth filtration for ; whole exome or other targeted sequencing data ; isSkipDepthFilters = 0 ; ; strelka will not accept input reads above this depth (they will be skipped ; until the depth drops below this value). Set this value <= 0 to disable ; this feature. Using this filter will bound memory usage given extremely high ; depth input, but may be problematic in high-depth targeted sequencing ; applications. ; maxInputDepth = 10000 ; ; If the depth filter is not skipped, all variants which occur at a ; depth greater than depthFilterMultiple*chromosome mean depth will be ; filtered out. ; depthFilterMultiple = 3.0 ; ; Somatic SNV calls are filtered at sites where greater than this ; fraction of basecalls have been removed by the mismatch density ; filter in either sample. ; snvMaxFilteredBasecallFrac = 0.4 ; ; Somatic SNV calls are filtered at sites where greater than this ; fraction of overlapping reads contain deletions which span the SNV ; call site. ; snvMaxSpanningDeletionFrac = 0.75 ; ; Somatic indel calls are filtered if they represent an expansion or ; contraction of a repeated pattern with a repeat count greater than ; indelMaxRefRepeat in the reference (ie. if indelMaxRefRepeat is 8, ; then the indel is filtered when it is an expansion/contraction of a ; homopolymer longer than 8 bases, a dinucleotide repeat longer than ; 16 bases, etc.) ; indelMaxRefRepeat = 8 ; ; Somatic indel calls are filtered if greater than this fraction of ; basecalls in a window extending 50 bases to each side of an indel's ; call position have been removed by the mismatch density filter. ; indelMaxWindowFilteredBasecallFrac = 0.3 ; ; Somatic indels are filtered if they overlap ’interrupted ; homopolymers’ greater than this length.
