  • 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:

    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!

    Thanks,
    Marisa

    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.

          Essential Discoveries and Tools in Epitranscriptomics
          by seqadmin


          The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist on Modified Bases...

          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...
