    thanks your answers!and I met another problem,after the mira_assembly,annotate_orfs,how to do the next annotate step ,if there any file to introduce the ngs_backbone annotate usage,thanks !
    best wishs!

    Hi lyuan,
    Few releases ago we removed mira assembly analysis from ngs_backbone. It takes to long and requires a lot of memory and sometimes (In our case ) you have to run it in another more powerful machine.

    If you need to assemble the reads you can download mira[1] and run it outside of ngs_backbone.
    Ngs_backbone helps you preparing the input files(renaming and joining) to run mira.

    Use prepare_mira_assembly for that.

    dear sir/madam
    I have use the -a prepare_mira_assembly -a mira_assembly
    And I found there is nothing in the /home/ngs_user/ngs_workshop/maize/assembly/20111115_0204/result dir,the dir like this:
    ngs_user@ngsmachine:~/ngs_workshop/maize$ ls -l
    total 24
    drwxr-xr-x 4 ngs_user ngs_user 4096 2011-11-15 03:04 assembly

    ngs_user@ngsmachine:~/ngs_workshop/maize/assembly/20111115_0204/result$ ls -l

    I found there is no mira soft in the
    /usr/local/lib/python2.6/dist-packages/ext/bin/linux/64bit dir

    Or you can tell me how to use the ngs_backbone assembly the EST reads
    wait your answers!

    Best regards,

    started a topic ngs_backbone



    We have created a tool to analyze NGS sequences and we think that it might be of some interest f
    or some of the seqanswers members. We are using this tool in non model species to:
    - clean sanger, 454 and illumina sequences,
    - assemble transcriptomes (using mira),
    - map reads to a reference genome,
    - call SNPs and indels,
    - filter SNPs and,
    - annotate sequences (descriptions, GO terms, SSRs, etc.)

    This software is written in python and released under the aGPL licence. Right now we consider it
    beta software and although we're using it in several of our projects you can find some rough ed
    ges when using the initial release. You can find more information at the ngs_backbone site.

    If you try it out we would like to hear from you.

    Best regards,

    Jose Blanca
