Hi, thank you for all the work you put in BBmap. I'm looking for a paired-end read merger, and I came across bbmerge.sh What I need is currently not supported I think, but maybe it could be added in the future? I have ultra-deep sequencing data for a 100bp region. The size of the DNA-fragments was short, so that forward and reverse read both cover the full 100bp. I would like to merge forward and reverse reads for this 100bp region and only keep matching bases, all non-matching bases should be replaced...
