  • BFAST memory error in postprocess

    Hello, I have a set of 85-bp long solexa reads and I have already used BFAST match, local align, an postprocess (with -a 3 option) successfully.

    I am now trying to filter the multi reads using the -a 4 option and am getting a memory error message.

    This is the command I am using:

    /bfast postprocess -f /filepath/TAIR9_chr_all.fas -i /filepath/bfast.aligned.split1_1_ZT0.baf -a 4 -O 1 > /filepath/bfast.reported.split1_1_ZT0.sam

    This is the error message I am getting:

    Checking input parameters supplied by the user ...
    Validating fastaFileName /filepath/TAIR9_chr_all.fas.
    Validating alignFileName /filepath/bfast.aligned.split1.baf.
    Input arguments look good!

    ***** Exiting due to errors *****

    This is the message I am getting with just this specific file. With other split file I am getting the message "line 3: 1182 Segmentation fault" (although the line is different depending on the file)

    I cannot figure out what this means and would appreciate any advice!

    Try posting a test case to the bfast help mailing list ([email protected]). I would be happy to help over there.

      I am not sure if this could be the problem, but it may be that I did all the other processing with version d and I am now using version e for the step in my above post? I will try doing everything with the new version for just one of my 12 libraries to see if it works.

        It could be. Use definitely the latest version. If you still have the problem send over some data so the bug can be track down.
