    Problems importing GFFv3 Annotation into SeqMonk

    I am using SeqMonk version 1.0 and trying to add annotation files in GFFv3 format available at ftp://ftp.ncbi.nlm.nih.gov/genomes/Sus_scrofa/GFF/

    Name Size Date Modified [parent directory]
    ref_Sscrofa10.2_scaffolds.gff3.gz 13.3 MB 3/7/12 9:26:00 PM
    ref_Sscrofa10.2_top_level.gff3.gz 13.0 MB 3/7/12 9:26:00 PM

    When I import them into SeqMonk, receive the following error after selecting FILE --> IMPORT ANNOTATION --> GFF/GTF:

    -----
    Request Generated Warnings...

    There were 530303 warnings when processing your request - showing the first 5000

    Couldn't find a chromosome called NC_010443.4
    ...

    ------

    It seems that the first column should be a chromosome designation (e.g. Chr1), but the GFFv3 format does not have this information in column 1.

    The SeqMonk changelog states that "Feature import from GFFv3 and GTF files" is supported, so I am not sure what my mistake is.

    Can anyone please help me with this?
    Thank you,

    Reply to Nine Things a Sample Prep Scientist Thinks About Before Sequencing

    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...
