Do the default parameters of Bowtie2 (sensitive: `-D 15 -R 2 -L 22 -i S,1,1.15` (default in `--end-to-end` mode)) provide good enough results to publish for assembling Illumina HiSeq unpaired 101 bp reads to a reference chloroplast genome? I don't know how to change parameters and wouldn't know what to change them to even if I could. The default parameters seem to be giving good results. Any suggestions?

It kind of depends on the question you are trying to answer. obviously. But I would say the answer is yes, there's no pressing need to change the params unless you have a specific reason to. It's fairly key to know the % of reads that have mapped successfully, and it's also worth examining the alignment (e.g. samtools tview or a windowed viewer like Tablet) to check there are no obvious misalignments.

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...
