A question about definition of "seed" in bwa and bowtie
As topic ,my question about definition of "seed" in bwa and bowtie , because it can be adjust in parameters.
If every one know please let me know! thaks!
Best regard!

from the bowtie manual : http://bowtie-bio.sourceforge.net/manual.shtml
-n/--seedmms <int> : Maximum number of mismatches permitted in the "seed", i.e. the first L base pairs of the read (where L is set with -l/--seedlen). This may be 0, 1, 2 or 3 and the default is 2. This option is mutually exclusive with the -v option.
-l/--seedlen <int> : The "seed length"; i.e., the number of bases on the high-quality end of the read to which the -n ceiling applies. The lowest permitted setting is 5 and the default is 28. bowtie is faster for larger values of -l.

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, detection...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
