  • Understanding glf format (Dindel)

    Hi, I used the Dindel (Illumina data), but I had some problems.
    In the last step I got a VCF file empty. I am wondering if the filtration criteria in the final step was very strict and I did not have any result (indels), or if there is some problem in my glf files.

    There is no information about the meaning of each of the columns of the glf files (in the manual, paper or in the internet). I used the options for pooled samples (I have a pool of 10 individuals in 1 bam file).

    For example (one of my glf file)

    msg index analysis_type tid lpos rpos center_position realigned_position was_candidate_in_window ref_all nref_all num_reads post_prob_variant qual est_freq logZ hapfreqs indidx msq numOffAll num_indel num_cover_forward num_cover_reverse num_unmapped_realigned var_coverage_forward var_coverage_reverse nBQT nmmBQT mLogBQ nMMLeft nMMRight glf

    Questions
    1) In my interpretation the quality score (phred score) is the "qual", is it correct? Because this is one of the criteria selection and in this column I got only "NA".
    2)"num_indel" is the number of indels that I got? because I had only "NA" again..
    3) "est_freq" is the allele frequency of the indel?
    4) What is the "msq"?
    5) "rpos" is the position in the reference sequence or in the realigned sequence?
    6) What is "lpos"?
    7) What is important to check in these columns?
    8) What is the last column?

    Someone could help me? Thanks

    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...
