  • PSMC, having to generate diploid.psmc file

    Hi there,
    I have downloaded fasta assembly from hamster:


    and paired end raw reads:


    I aligned the using bowtie2 aligner. my commands are as follows:
    bowtie2 -x hamster_index -1 SRR40216_1.fastq -2 SRR40216_2.fastq -S hamster.sam
    samtools view -bS hamster.sam > hamster.bam
    samtools sort hamster.bam hamster.sorted
    samtools mpileup -C50 -uf GCF_000349665.1_MesAur1.0_genomic.fna hamster.sorted.bam | bcftools call -c - | vcfutils.pl vcf2fq -d 10 -D 100 | gzip > hamster.diploid.fq.gz
    fq2psmcfa -q20 hamster.diploid.fq.gz > hamster.diploid.psmcfa
    psmc -N25 -t15 -r5 -p "4+25*2+4+6" -o diploid.psmc hamster.diploid.psmcfa
    psmc2history.pl diploid.psmc | history2ms.pl > ms-cmd.sh (here problem arises: ** Illegal division by zero at /usr/bin/history2ms.pl line 48, <> line 31.)

    then I checked my diploid.psmc file and found there are two columns with values only 0. (attached)
    Any idea why I am getting this??? I followed same pipeline for other organisms like horse, dog etc. and got good results.

    Best Regards

    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...
