    Hey Guys

    Just pushing this once more. I would appreciate if you could share some insight on finding long/short indel in GA data and also detecting long inversions.

    Thanks

    Hey Collindaven

    Thanks for sharing your insight. I unfortunately work only on the informatics side only and till now haven't heard back from the team for whom we did the insilico indel analysis in the past. So I dont know the false positive rate.

    What I hear and read from papers that people are finding it more useful to do indel analysis with paired end data as it gives more room to find long indels based on the known evidence of the expected distance where the read 1/2 should map.

    Thanks!

    Hi,

    We haven't got into this massively as we only have 36 bp single end reads from bacteria.
    However initial results have been disappointing. We used Shrimp1 for alignment and attempted to verify 3 small <5bp indels in the wetlab. All failed, despite having 10+ reads predicting their presence.

    We tried to verify another 8 by Sanger sequencing. It turns out the sequencing was poor, and these are associated with tricky repeat rich bacterial regions.

    It seems the aligners are having some trouble with indels.

    What has your experience been like ?

    Finding Indel's and long inversions in GA data

    Hi All

    I am looking for tools to find indel in GA data (short and long) and also look for large inversions after de novo assembly and comparing to reference genome.

    In the past I have used VarScan and samtools for finding indel but just wondering if people are using other software for finding indels and ways in which large inversion could be detected.


    PS: I have looked at the software wiki but would like to try tools based on your experience.

    Thanks!

    Exploring the Dynamics of the Tumor Microenvironment
    by seqadmin




    The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

    Exploring Human Diversity Through Large-Scale Omics
    by seqadmin


    In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
