Is YACHT applicable to ONT reads?

dkoslicki commented 3 months ago

We did not test it on ONT reads, but there is nothing technical stopping YACHT from at least running on ONT reads. My concerns would be 1: ONT reads have a different error profile that can more severely violate the point mutation assumption and 2: YACHT is meant (by default) to work with large (read: Illumina) sequencing sets. For smaller ones, you could decrease the scale factor (eg. scale = 10), but would need to be sure your training database matches. If you have a benchmark/ground-truth ONT data set, we'd definitely be interested in hearing what you find!

Thanks a lot
