WebSep 20, 2016 · samtools rmdup removes potential PCR duplicates: if multiple read pairs have identical external coordinates, only retain the pair with highest mapping quality. -s Removes duplicate for single-end reads. By default, the command works for paired-end reads only. Remove reads with multiple mappings using samtools and grep. Web(A) All reads are stored in a hash table with a unique id. A second hash table contains the ids for the read start = k-mer parameter (default = 38) of the corresponding read. (B) Scope of search 1 is the region where a match of the ‘read start’ indicates a extension of the sequence. All these matching reads are stored separately.
