how to calibrate CTC-CRF model base qualities?

[lpryszcz]

Hi, how to calibrate bonito trained models so base qualities correspond to expected error rate?
For example config.toml for RNA004 sup models uses:

[qscore]
scale = 0.9
bias = -0.1

How were those values obtained?

any update on this? we're in the review process of basecalling model trained with bonito and we are unable to calibrate qscores therefore qscores from CTC-CRF models are not comparable with older models (flip-flop).
I have opened similar issue in dorado repo
