  • blastn m0 -> m8 bug

    Hi,all

    Does anyone meet this question.

    Blastn Error:

    Error :m=0, E-value = e-141,Gaps=3, However when m=8,E-value is 2e-141, Gaps=2

    Tool:Blast

    The version number:blast-2.2.26 /blastn

    Parameter:default

    Query :DNA sequence, 1477 bp, test.fa

    Database: Rv0002, 1209 bp, Rv0002.fa

    Output:

    m=0

    Score = 490 bits (247), Expect = e-141

    Identities = 263/266 (98%), Gaps = 3/266 (1%)

    Strand = Plus / Plus

    m=8

    test Rv0002 98.87 266 0 2 944 1206 178 443 2e-141 490

    Thanks very much!

    Have you tried the current release, BLAST+ 2.2.29, which may well have fixed this?

            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...
