    Mosaik Aligner problem with SOLiD sequences

    Hi all,
    I have installed Mosaik 1.0 on two desktops to map SOLiD colorspace reads. On one desktop, the Aligner never quite worked: it would always choke on some input read or other with a message like:

    "ERROR: Unknown combination found when converting to basespace: [T] & [-]"

    I traced the first offending read in one of the input datasets, and there was nothing special about it.

    On the other desktop, Mosaik Aligner has been working fine, with only a recent issue similar to the Error described above: I tried to use the option where the reference genome has IUPAC ambiguity letters that allow more matches to them (e.g. an R in the reference could match to both an A or G in the read without a penalty).

    But the runs don't seem to work, the aligning process returns immediately errors like "Unknown combination found when converting to basespace: [Y] & [G]" (like I described above, always happes with my other installation).

    Anyone seen this issue? Ideas how to resolve it?

    Thanks

    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...
