I am using Ion Torrent 200bp sequencing and looking into aligners. Any opinions as to which of the two (bowtie, bowtie2) may be a better choice? Thanks

Bowtie cannot tolerate indels, so it should never be used for Ion Torrent alignment. So between those two, Bowtie2 is the only viable choice, though personally I'd recommend BBMap. The best aligner may depend on your experiment type and organism of interest. -
Thank you very much.... I will look into BBMap as I am not familiar with that.

NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification,...10-30-2026, 06:46 AM -
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
