  • blastall error

    Hello experts,

    I have had no problem running blastall using the command below so far.

    blastall -i query.fa -d database -p blastx -e 1e-5 -a 8 -o output.txt

    And all of sudden, I am getting the same warning message as below. I even tried the same query file that was run fine without problem last time but it wasn't run fine this time generating the warning message.

    [blastall] WARNING: contig-100_131270: Could not calculate ungapped Karlin-Altschul parameters due to an invalid query sequence or its translation. Please verify the query sequence(s) and/or filtering options.

    Could anyone give me any comment on this? Any help would be greatly appreciated.

    What is the sequence for contig-100_131270, can you see anything odd like invalid nucleotides?

      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...

      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...
