  • Can prinseq do trim_left on paired-end?

    When using prinseq on paired end data and I want to trim the 5' end of both reads by 10 bases, how can I do it?

    I've tried -trim_left 10 because I assumed it would do the same for both. Maybe thats wrong and it would trim from 5' of _1 and 3' of '2?

    At any rate it doesn't seem to trim them at all for either file when I run the filtered reads through fastqc. Anyone ever try this or know how to do it correctly? Thanks!

    Don't know about prinseq but bbduk.sh from BBMap certainly can. Use forcetrimleft=10 option.
