I am trying to run CountCovariates in GATK. I downloaded the most recent dbsnp file from the broad institute site. The problem is it is not sorted in chromosomal order. I have vcf-tools installed and tried to sort using the -c command. It is telling me "Obsolete version of sort command installed, please run without the -c option." But, if I type in vcf-sort -h , the usage says the -c is available. I have checked to make sure we have the most recent version. I don't find the vcf-tools website to be very helpful. Could someone point me in the right direction or do you know where I can download a sorted vcf file? Is there another program that I can use?

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...04-04-2024, 04:25 PM -
Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...03-22-2024, 06:39 AM
