Strelka
Strelka identifies single nucleotide variants (SNVs) and small indels using the following steps:
|
•
|
Read filtering—Filters out reads that fail quality checks. |
|
•
|
Indel calling—Identifies a set of possible indel candidates and realigns all reads overlapping the candidates using a multiple sequence aligner. |
|
•
|
SNV calling—Computes the probability of each possible genotype given the aligned read data and a prior distribution of variation in the genome. |
|
•
|
Indel genotypes—Calls indel genotypes and assigns probabilities. |
|
•
|
Variant call output—Generates output in a VCF file and a compressed genome variant call (gVCF) file. |
