  • bfast postprocess "AlignedEntryGetAlignment" error

    Dear all,

    unexpectedly, I am getting the following error when trying to run bfast postprocess (alignment of 95 bp Illumina paired-end reads):

    Code:
    bfast+bwa-0.6.4e/bin/bfast postprocess -i t_8.baf -f hg19_indices/hg19.fa -a 3 -z -A 0 -R -O 1 -n 4 -U > t_8_alternative.sam

    Suggestions are very much appreciated.

    Please submit a test case to the bfast mailing list.

      Dear all and Nils,

      when preparing the test set, I realized that the reference genome used for bfast postprocess was not the same I had used for alignment after all. (Too many editions of the hg19 around!) That is what caused the error.
      However, as so often, to post the problem helped me to solve it .

      Sorry for the confusion!

      cheers,
      Sophia

          what does "avgMismatchQuality" mean?
          does it refer to something with the base quality of mismach base?

            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...

            Strategies for Sequencing Challenging Samples
            by seqadmin


            Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
