  • GATK error "Annotations with zero variance"

    Hi,

    I am wondering if anyone has ever come across this GATK error during the VariantRecalibrator step

    Yes, I've seen it. The error message says "Please do NOT post this error to the GATK forum unless you have really tried to fix it yourself." so I had assumed that it was my mistake, something wrong with the command line. I reran VariantRecalibration with only the minimum of annotations, e.g. -an BaseQRankSum -an FS, and the error went away, so I assume it is when you are trying to use an annotation which only has minimal representation/information in the training variants in the input callset.

      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...
