    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.

          Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
          by SEQadmin2



          CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

          Despite this, “CRISPR helped turn genome editing from a specialized technique into

          Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
          by SEQadmin2


          Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

          Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
          by SEQadmin2



          Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.
