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?

NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification,...10-30-2026, 06:46 AM
