  • 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?

        Thanks a lot ,it's OK,I think may they have the different algorithm.

            Essential Discoveries and Tools in Epitranscriptomics
            by seqadmin


            The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist on Modified Bases...

            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...
