  • problem with auto_annovar

    I am trying to analyze some exome data using auto_annovar program. It works brilliantly till step 8. After Step-8, it generates a file but then it stop. During the step-8 processing, it says "fGrep: Writing output" and at the end the final message is "fGrep : Write error". Step-8 file contains the variants but with no gene names.
    i am not able to map the variants to the relevant genes. I checked my Humandb database, it seems to contain all the relevant files. Can anyone please kindly help me with this. Thanks a lot

    I am experiencing an issue with auto_annovar script too.
    I am using annovar for a few months. Until now, I used script, with different parameters separately, -geneanno, -regionanno, -filter,...
    Now, I would like to try auto_annovar script, but I am stuck at the first step:

    perl -model recessive $dir/$file humandb -build hg19 -step 1
    NOTICE: the --ver1000g argument is set as '1000g2010nov' by default
    Error: the required database file humandb/hg19_ALL.sites.2010_11.txt does not exist. Please download it via -downdb argument by
    I cannot find what this hg19_ALL.sites.2010_11.txt database is... I check the script and it is not mentioned in it.
    I try to donload it:
    perl -downdb hg19_ALL.sites.2010_11.txt humandb -build hg19

    Does someone know what is this file and where I can find it?


    ps: I am using the version of March 2012.

      Try to include "-webfrom annovar" when downloading. Also, try "1000g2010nov" instead of "hg19_ALL.sites.2010_11.txt".

        Thank you for your answer, your remark put me on the right way: I have downloaded 1000g2012apr and not 1000g2010nov, so I only needed to change the name inside the script.

        I managed to run the three first steps, but I don't really understand the outputs. I get files concerning almost all the steps: step4, 7, 8, 9, I don't know why, maybe they are here by defalut. Moreover, I cannot open the file .genelist, which seems to be the final file

          I don't actually use the auto_annovar script, I just use the script and do my own filtering from that, so I'm not sure exactly what you should get.

            Ok, thanks. I will try script since I don't really want to follow all the steps of

              Advanced Tools Transforming the Field of Cytogenomics
              by seqadmin

              At the intersection of cytogenetics and genomics lies the exciting field of cytogenomics. It focuses on studying chromosomes at a molecular scale, involving techniques that analyze either the whole genome or particular DNA sequences to examine variations in structure and behavior at the chromosomal or subchromosomal level. By integrating cytogenetic techniques with genomic analysis, researchers can effectively investigate chromosomal abnormalities related to diseases, particularly...

              How RNA-Seq is Transforming Cancer Studies
              by seqadmin

              Cancer research has been transformed through numerous molecular techniques, with RNA sequencing (RNA-seq) playing a crucial role in understanding the complexity of the disease. Maša Ivin, Ph.D., Scientific Writer at Lexogen, and Yvonne Goepel Ph.D., Product Manager at Lexogen, remarked that “The high-throughput nature of RNA-seq allows for rapid profiling and deep exploration of the transcriptome.” They emphasized its indispensable role in cancer research, aiding in biomarker...
