Prograns to idIdentify core genes under negative selection
I got multiple genomes for different gram-negative bacteria. What program could I use to identify specific core genes under negative selection but with smaller regions that exhibit positive selection? Is there any limitations/problems I might encounter along the way?

Do you have annotated genomes? Or just the assemblies?
If you have annotations, your project is quite similar to one project I'm working on right now...
My strategy is:
blast all genes vs each other
use R to look for gene clusters (then, you can apply the thresholds you want to decide whether a cluster has to be reported or not...)
If you don't have annotations, I would do more or less the same, instead that I would first try to make annotations using a software like glimmer...

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 -
Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.
We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing...
