Description
Simple
Mutation percentage from
Select this option to set a single mutation percentage range for all variant types, and then specify the range.
Note: Applicable only for setting a range of values with a minimum value that are greater than or equal to the value that specified in the Project Wizard. See Mutation percentage <=.
Matrix
Select this option to set independent thresholds for each variant type.
Note: Applicable only if setting a value that is greater than or equal to the value that you specified in the Project Wizard. See Mutation Filter settings.
Mutation percentage
For the indicated variation type (SNP, Indel, or Homopolymer Indel), a variation between the aligned reads and the reference sequence at a given position of the reference must occur at a frequency that exceeds this value, or a variant is not called at the position.
SNP allele count
For the indicated variation type (SNP, Indel, or Homopolymer Indel), the total number of reads with the variant allele must exceed this value, or a variant is not called at the position.
Total coverage count
For the indicated variation type (SNP, Indel, or Homopolymer Indel), the total number of reads at a given position must exceed this value, or a variant is not called at the position.
Ratio of homopolymer length change
Ratio = |(ref homopolymer length –alt homopolymer length)|/ref homopolymer length. If there are multiple alt lengths, then the ratio is calculated for each alt and the largest ratio value is used.
