It takes a tumor bam and a normal bam and compares the two to determine the +differences. It outputs a file in a format very similar to Samtools consensus format. It uses the genotype likelihood +model of MAQ (as implemented in Samtools) and then calculates the probability that the tumor and normal genotypes are +different. This probability is reported as a somatic score. The somatic score is the Phred-scaled probability (between 0 to 255) +that the Tumor and Normal genotypes are not different where 0 means there is no probability that the genotypes are different and +255 means there is a probability of 1 – 10(255/-10) that the genotypes are different between tumor and normal. This is consistent +with how the SAM format reports such probabilities. + +bam-somaticsniper [options] -f ref.fasta tumor.bam normal.bam snp_output_file + +Bam files must contain LB tag in @RG line. +Picard tools can be used to add lines to BAM headers. + +----- + +**Required Parameters** + +:: + + -f FILE REQUIRED reference sequence in the FASTA format + +----- + +**Options** + +:: + + -q INT filtering reads with mapping quality less than INT [0] + + -Q INT filtering somatic snv output with somatic quality less than INT [15] + + -p FLAG disable priors in the somatic calculation.
