According to best practice variant detection if You have multiple sequencing of the same sample from 2 different runs You need to merge bam files prior to realigner/indel realigner/mark duplicates. Is it possible to merge bam files that were already realigned/marked duplicated (per each bam separately) ?

Realignment is performed on a set of reads. If you merge two BAMs and add reads to a locus then realignment is needed. Same goes for marking duplicates or recalibrating bases.

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...
