I want to call SNPs in GATK using the BAM file produced by GS Reference mapper , bu the problem with BAM file is it does not contain the read group so how to add read group in the bam file of 454 sequencing data and whether or not PICARD and GATK can be used to call SNPs from 454 sequencing data. Till now I was using samtools but now my task is to compare the output of Samtools and GATK. ANy help will be appreciated

I will work on the next post so it makes more sense.

thanks for reply but my concern is with 454 sequencing data because I have not came across any good reference which has used GATK for SNP calling from Roche 454 sequencing data. Can you please brief me about the proper pipeline of SNP calling starting from adding of the read group to the variant calling in GATK using 454 sequencing data?

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...-

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...-
