Hi all,

I am using RetroTS.py in a bash terminal to turn respiratory and cardiac tsv.gz files into regressors for 1st level analysis.
I kept getting this error and any suggestion is greatly appreciated!

RetroTS.py
-phys_file sub-test_ses-test_task-reward_recording-cardiac_physio.tsv.gz
-phys_json sub-test_ses-test_task-reward_recording-cardiac_physio.json
-v 2
-n 72
-prefix physio_card_regressors.1D

#output

** return yi.reshape((yi.shape[0], -1))**
ValueError: cannot reshape array of size 0 into shape (0,newaxis)

I am following the suggestions from this post: [neurostars.org]
Same error with respiratory files. Specifying p instead of json file yielded the same error.
Upon inspection, physio files look normal (two columns: timepoints, amplitude).
Please find the linked de-identified physio and json files for error replication.

Thank you all!
