  • 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.

          Current Approaches to Protein Sequencing
          by seqadmin


          Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

          Strategies for Sequencing Challenging Samples
          by seqadmin


          Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
