What format do they follow then? What is a good suggestion to filter NanoPore reads, if they should be filtered at all?
NanoPore quality scores:
The Phred quality score defines the quality of each base in the sequence, with values from from 0 to 93. The score is calculated as: Quality score = -10 x log(Pe) where Pe is the estimated error probability for each base. For example, an error of 1 in 100 will give a q-score of 20. The q-scores are then encoded in the Sanger format using ASCII, with values of 33 to 126. The quality is then shown as a single character per base.

I would unassign me from this. Any volunteer taking the responsibility for this issue?
Disable length trimming based on quality for NanoPore reads. NanoPore quality scores do not follow PHRED scores.
