  • Challenging read mapping problem

    Hi,

    I have about 70Gbp of paired-end data from potato [1] that I'd like to map to one of the chromosomes (chr04). I only want pairs where one end or the other, or both, matches chr04.

    Aside from the scale of the problem, the format of the files is a pain, because each pair is in a different file.

    Any tips on how to do this (efficiently)?

    A prize goes to the best answer ;-)


    Cheers,
    Dan.

    Most of the aligners handle paired data in different files. I do not think it is a problem. Use BWA or other aligner program.
