+
+**What it does**
+
+The purpose of this program is to identify single nucleotide positions that are different between tumor and normal 
+(or, in theory, any two bam files). 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.
