    So what I understood is run the SNP pipeline for both WT and mutant the same way and after we get the SNP file filter the common ones and focus on the SNPs different in both.
    yes, you'd just have to download the strain specific mutations VCF from dbSNP to find the mutations that are common to your wild-type strain because of the strain differences between wildtype and mouse reference genome.

    I think you'd go through the SNP calling in the same way for both sets of samples. (i.e.., mapping to reference genome and calling SNPs using GATK/Samtools etc).

    Then you could look at the common SNPs in dbSNP for the wild type strain and flag them in your wildtype variant files as being down to strain difference and proceed with the analysis for the remaining variants.

    started a topic SNP calling from multiple genotypes

    SNP calling from multiple genotypes

    Hi
    I am new to snp discovery analysis. We recently sequenced a wild type and two mutant lines using illumine. The wild type is different from the reference genome available. Can anyone suggest a pipeline for identifying the SNPs in WT-Mutant.

    Do we need to assemble our WT before calling SNPs in mutant or can we use the reference genome to map the reads from both the WT and mutant and call the SNPs.

    Appreciate your help.
    Thank you

    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...
