@gaoxiangcao I am working on modification calling and got up to preprocess to work. I'm currently resquiggling but it's taking a while to run. Here are the steps I have done so far that are working.

1. Basecall with guppy
2. Create new environment and install tombo with miniconda.
3. Use multi_to_single_fast5 (from ont_fast5_api) to convert your guppy multi-fast5 files (default output) to single-fast5.
4. Use the python code to fix your sequencing_summary.txt file

#!/usr/bin/python3

with open('sequencing_summary.txt') as file, open('sequencing_summary_fix.txt', 'w') as outfile:
    header = next(file)
    outfile.write(header)
    for line in file:
        line = line.split()
        line[0] = f"{line[1]}.fast5"
        line.append('\n')
        outfile.write("\t".join(line))

5. Run tombo preprocess
6. Run tombo resquiggle. Make sure you have the hdf5 plugin in order for this to work. Use the steps below for linux if you don't.
