I am working on Next gen sequenced data. I have used sam tools for the analysis and completed generating variant pileup. Can anyone suggest how to add dbSNP annotations and do cSNP prediction using samtools?? Or can you even suggest any other tool to do this??

I use a program called annovar. It'll convert vcfs or pileups from samtools and convert them into its own format. It downloads the gene and protein data from UCSC, so you'd have to construct your own data if you were working in an organism that wasn't in their database. I think annovar can probably handle a dbSNP file too. Or Bedtools could intersect your vcf with a .bed file of dbSNP snps.
I work with bacteria, and I cobbled one together by blastxing altered sequence against proteins, and parsing the output.

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, detection...Yesterday, 06:46 AM -
Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?
Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating...10-14-2026, 09:55 AM
