Im working with paired-end RNA-seq data, and for my purpose I map the forward and reverse reads individually. What is the easiest way to assemle reads into a single alignment file while forcing the original direction to be preserved? So e.g. I want forward and reverse information of reads in final alignments.

You know that aligners that make .sams will natively figure out how to combined your paired end data so that you still know which read cam from which fastq, right?
If you really have to work with these bams, set the flags yourself to indicate which come from read1, and which come from read 2, then merge the .bams.

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...
