fMRIPrep run numbers not the same as in the raw BIDS data

,
1

Hello,

In my BIDS dataset, I have named the func runs run-01, run-02 etc. But after running fMRIPrep, the run numbers are changed to run-1, run-2 etc.
Why that? Is it possible to keep the run numbers as they were in the BIDS dataset?

What version of fmriprep are you using?

this is an old bug that was fixed in version 0.22: run index not carried over from source data to derivatives · Issue #2666 · nipreps/fmriprep · GitHub

Thanks for the info! I didn’t find this in my search.
I should have stated my version - 21.0.1.
I will rerun with a newer version then.
