    samtools sort

    Hello,
    I am trying to sort a large bam file, actually split in two, with samtools sort
    I use -m 10000000000 so the job creates 8 sorted files of about the same size, plus a smaller last one.
    At the end of the job, samtools sort give the message "core_sort_merge 9 bam files" and it stays like that for a while before the screen starts showing multiple caracters one after the other.

    My question is, can I assume the job was completed?
    My command-line was
    samtools sort -no -m 10000000000 inpunt.bam output.prefix &

    Any help appreciated.

    Probably the best thing to do is just check to make sure you have the same number of reads in the output files as you do in your input.

    Not sure if you are interested but we also have a parallelized implementation of "samtools sort" that combines the merge/sort step. Its at http://www.github.com/adaptivegenome/openge. It's open source and there are also binaries for convenience...

      Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.

      Nine Things a Sample Prep Scientist Thinks About Before Sequencing
      by SEQadmin2


      I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

      Here are nine questions we think about, in roughly the order they matter, before...
