I'm having the same issue... Was there a solution identified?

[schmittel]

Oh I figured it out. Needs the histogram.py script - didn't see that one. And the paths need to be matched with the *.sh script.

Hi @schmittel, I'm having the same issue but didn't quite understand your solution. What do you mean by 'needs the histogram.py script' and 'paths need to be matched'? I see the histogram script in the same folder as the read_info_histogram.sh, but don't know what is missing for the latter script to work. Thanks

I'm also having this issue. @tauanajc did you figure it out?
