We have sequenced a transcriptome of a species who does not have a sequenced genome, using 454 and our initial goal is to find a set of ESTs that represent genes. The 454 reads were assembled using Newbler 2.5 and the initial assembly gave ~26000 isotigs and 18,000. Contigs. After talking to the several people, I used CD-Hits program to combine the isotigs, contigs and singltons that were not assembled. After combining these sequences, I got ~4000 isotigs, ~17,000 contigs and ~30, 000 Singlton that were not assembled. Is this the correct way to do this? I couldn’t find any publication that has mentioned this method.

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...
