    annovar output problems

    Hi,

    I have trouble making Annovar’s gene annotation tool work well.

    I am working on a virus, so had to build the reference by myself following Annovar’s website indications. I so build the refGene file, the refLink one, and through Annovar’s retrieve_seq_from_fasta.pl, the fasta file. I then run a vcf file, already passed through the convert2annovar.pl script in order to prepare it correctly for the input, and had as a result every variant listed as “intergenic”.

    I am working on a Mac OSX 10.6.8, but if needed have access to a new Linux environment.
    I tried with both the old version of Annovar and the recently released one (few days ago).

    The script has been called like this:

    /path/.../annotate_variation.pl --geneanno --outfile sample --dbtype refGene --buildver NC_XXXXX sample.annovar /path/.../NC_XXXXX/

    File samples (I’ll just show one line. Notice that the variant I show is exonic):

    refGene.txt file (Reference):

    94 U11 gene NC_XXXXX - 18924 21578 18965 21578 1 18924 21578 . U11 gene unk unk 2

    refMrna.fa file (Reference):

    >U11 gene Comment: this sequence (leftmost exon at NC_XXXXX:18924) is generated by ANNOVAR on Fri Jun 28 12:06:03 2013, based on regions speficied in /Users/Marco/Desktop/NC_XXXXXdb/NC_XXXXX_refGene.txt and sequence files stored at /Users/Marco/Desktop/NC_XXXXXdb.

    sample.annovar file (input):

    NC_XXXXX 20309 20309 A G hom . 5

    sample.variant_function (OUTPUT):

    sample.exonic_variant_function (OUTPUT):

    This file was empty.


    Thanks in advance for the help. If more info are needed, please do not hesitate asking me.

    Maybe someone here can help, but in the past I emailed the author of ANNOVAR and he got back to me quickly with help; so if you can't figure it out maybe email him.

      Yeah, that was my next step, but usually this forum works so well that I prefer to try first here.

      Thanks for the suggestion anyway

        how to build database in annovar for virus

        Dear Marco,

        I am also working on virus. How did you build the database.

        Can you please guide me in building the database for virus?

        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...
