  • best tool for indels?

    hello

    we have a sample with a 10 bases deletion and 2 nt insertion that is not detected with the following tools: eland-extended+Casava/bwa-gatk/bfast

    any suggestion on what else to try?

    thanks

    thats strange. Do you know why it is missed using those tools? Any others that were expected and found?

    Maybe you need to look at visualization of mapped reads in that region (using IGV or similar) to get an idea of whats going on. Is there even read coverage in that region..

      You may try stampy/novoalign+dindel. If that fails, your indels are intrinsically unable to be called.

        I'd break the question into two parts -- (1) are you seeing alignments of reads bearing the variant (2) are those reads leading to an indel call.

        Obviously if #1 fails then #2 can't possibly work.

          To give some context, could you let us know the size/nature of the reference genome, and the technology/readlength/yield of the reads?

            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...
