Describe the bug
Hi all, I am very new the bioinformactic space and I am setout to learn how to QC nanopore data. I have managed to install pycoQC but can not get it to run sucessfully. Can someone explain what TypeError is?

TypeError: unsupported format string passed to NoneType.format

I used commend pycoQC --summary_file sequencing_summary.txt -o testing.html

Desktop (please complete the following information):

• OS 14.6.1

I am facing the same issue. It seems that newer runs don't work anymore. I am using MinKNOW 24.06.8 with Dorado 7.4.13, pycoQC v2.5.0.3 installed in a mamba environment with Python 3.12.5.
