The different between fragment and reads? thanks anyway！
-
-
Fragment is an universal term for short DNA strings. Read is produced by sequencing machines. -
I would say in the case of paired-end reads, the fragment is the entire piece of which the ends have been sequenced, whereas the reads are just the sequenced parts. If that's what you're talking about.
Like cufflinks has "FPKM" fragments per kilobase per million instead of "RPKM" reads per kilobase per million.Comment

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...
