Problem with KeyError: 'chromosome'

[ChloeL2023]

Hi @snajder-r

Since I had R10 data and tried the f5c tool to generate the methylation tsv file similar as Nanopolish. The header of this tsv is:
chromosome start end read_name log_lik_ratio
chr1 10468 10470 5a459fff-cd92-4d3b-b50c-408aedd14609 -2.81
chr1 10483 10496 5a459fff-cd92-4d3b-b50c-408aedd14609 0.14
chr1 10524 10524 5a459fff-cd92-4d3b-b50c-408aedd14609 -0.75
...
However, I got the error like this:
0%| | 0/4 [00:00<?, ?it/s]
Traceback (most recent call last):

raise KeyError(gpr)
KeyError: 'chromosome'

The command to create m5 is: meth5 create_m5 --input_paths /path/to/meth/tsv --output_file aCGH29171.m5 && echo "done"

Could you help me solve this problem? Thank you so much!

Best regards,
Chloe
