  • Can Pindel applied to SOLiD data?

    Dear All
    Just want to know if anyone has relevant experiences in calling INDELS using Pindel on SOLiD data. We used Pindel on Illumina samples (bam files) with good outcome but now when we moved to SOLid data (bam files, already mapped to reference genome), all I got are empty output files

    I have very little experience with SOLiD data, can anyone share with me your experience in applying Pindel to SOLiD data? What procedure did u go through to get the results?
    Thanks

    Pindel expects the read orientation as in Illumina paired-end. There is one sam2pindel program to handle SOLiD data but performance is not guaranteed to be optimal.

      Thanks Kaiye for your suggestion

      However, I am still unable to convert the SoLID bam files into Pindel compatible format with the sam2pindel function. The reads in my SoLID bam file looks like this:

      I tried "samtools view -h input.bam | ./sam2pindel - output.pindel 250 sample 0"
      and the output "output.pindel" contain 0 reads somehow

      I even tried the newer version of sam2pindel with the "Illumina-PairEnd" at the end, it still generates 0 reads in the output file

      Any suggestion?
      Thank you

        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...
