Filtlong is a tool for filtering long reads by quality.
Filtlong is a tool for filtering long reads by quality. It can take a set of long reads and produce a smaller, better subset. It uses both read length (longer is better) and read identity (higher is better) when choosing which reads pass the filter.
The module takes summary statistics of number of long reads filtered and displays them in the General Stats table.
Sometimes, the Filtlong log message contains this:
Filtering long reads target: 123456789 bp reads already fall below target after filtering Outputting passed long reads
In these cases we cannot say for sure how many bases were kept. As such, this field is left blank. If you have a better solution, please suggest in an issue or pull request.
