  • exonerate - how to use multiple cores?

    Hello,
    I used this command to run exonerate:

    exonerate -m p2g -q uniref90_modified.fasta -t all_LGs/PcapLG_18.fasta --softmasktarget yes --showvulgar no --showalignment no --showtargetgff yes --showquerygff no --percent 80 " > LG18_exonerate_pcap.gff

    This only use one core. I have 32 cores.
    It's getting too slow.

    Thanks

    I would try running it in server-client mode:

      I tried exonerate-server too. This one is also slow.

        exonerate is simply a slow program. You can split the query file up into 32 files and run 32 exonerate commands simultaneously, then concatenate the results.

        exonerate comes with a a tool, fastasplit, for this purpose

          I tried that too. I made 100 parts. Running single file took more then 3 days and stopped, which means more then 300 days to go.

            GMAP might be suitable for your purposes (transcript mapping to GFF3), and is a lot quicker with good parallelization.

              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...
