IndexError: list index out of range when running remora dataset prepare due to k-mer table parsing

[iza-mcac]

Hello,
I'm encountering an error while trying to run the remora dataset prepare command. The issue seems to occur when loading the k-mer table provided (5mer_levels_v1.txt). Below is the command I ran and the traceback of the error:

Command:

remora \

  --refine-rough-rescale \
  --motif CG 0 \
  --mod-base-control

Error:
