    SOAP output format - description?

    Hi,

    I have searched the SOAP website and read the paper but I cant find a description for all the columns in the ouput.

    Col1 = Read Seq_ID
    Col2 = Read Sequence
    Col3 = Read Sequence Quality
    Col4 = ? I have the digit 1 here
    Col5 = ? I have the letter 'a' here
    Col6 = Read Length
    Col7 = Strand
    Col8 = Reference Seq_ID
    Col9 = Position of start of read alignment
    Col10= 0/1/2 - I think this is the number of mismatches?
    Col11= base change - cant work out this out eg G->10C7


    Can anyone fill in the blanks for me?

    Regards
    Aengus

    column 4 is uniqueness.

    if you gave it paired end data, a and b signify the two halves of the same paried end read. With single end data, its always a.

    Yes, column 10 is the number of mismatches. The base change the reference letter and its position, and the read's letter and its quality score. The output is a littel trickier with indels.

      I realize this is an old thread, but I had trouble finding the specifics as well. Ended up going to the SOAPv1 page, found the output file description there.

        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

        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...
