NanoPlot quality data

Question

[Wagner Daniel]

I would like to know what the quality ranges are for Nanoplot and what criteria are used to determine these quality ranges or obtained quality results. my results were:

sample 1
General summary:        
Mean read length:                569.0
Mean read quality:                14.0
Median read length:              221.0
Median read quality:              13.6
Number of reads:              18,713.0
Read length N50:               1,741.0
Total bases:              10,648,246.0
sample 2
General summary:        
Mean read length:               2,283.7
Mean read quality:                 14.0
Median read length:             1,390.0
Median read quality:               13.8
Number of reads:              161,819.0
Read length N50:                4,108.0
Total bases:              369,538,332.0

Is my quality data good or bad?

Don't compare nanopore data with Illumina quality scores. This data looks fine for nanopore.

If this is Nanopore long read data your "Mean read length" seems to be very low.
