NIFTI to BIDS conversion with multiple subjects in one session.

[JulianGaviriaL]

What is missing in the following code line to convert NIFTI to BIDS with multiple subjects in one session?
D:\software\pyproj\proj_name>bidsmapper raw BIDS -n '*' -p nibabel2bids

OS: windows 10 pro
Python: 3.12.6
BIDSCOIN: 4.4.0

Mhhh, it seems okay to me. We always have a prefix in the center where I work, so your use case is less well-tested. I do test it (see here), but apparently, not well enough. I assume that in your raw -> anat, etc folder you have .nii.gz files?

[marcelzwiers]

Perhaps it helps if you also specify an empty ses-prefix, i.e. -m ""?

[JulianGaviriaL]

Thanks marcel for replying:

Yes, I have .nii.gz files in the "raw -> anat", "raw -> func" folders.

Trials 1 and 2 yielded the following error message:

trial 1:

trial 2:
((bidscoin) D:\software\pyproj\proj_name>bidsmapper raw BIDS -n '*' -m"" -p nibabel2bids

Trial 3: Adding the "s" prefix to the subjects folders.

Step1:
(bidscoin) D:\software\pyproj\proj_name>bidsmapper raw BIDS -n "s"
It did not recognize the subjects in the nibabel window:

However, the data is well read in the "data browser" window:

Step2. I saved a template (bidsmap.yaml) with the nibabel2bids plugin. I ran again the editor with the nibabel2bids plugin:
It now reads the .nii files only from the first subject in "the nibabel mapping" window.

However, the second subject seems recognized. see console lines:

(bidscoin) D:\software\pyproj\proj_name>bidsmapper raw BIDS -n "s"

Sorry for my slow response, but in your last email you are showing two different windows, i.e. in the first there is no Nibabel mappings tab, but in the second (where you are showing the file browser) there is. So I'm not sure what is going on, but my guess is that by re-running the bidsmapper you got it to work, right? Your question about the second subject is nothing to be worried about, in fact it is a feature: in BIDScoin you only specify the mapping per unique datatype, not per subject (which can become incredibly long)

Unfortunately, I cannot be of much assistance because I'll be away for the coming three weeks....

[marcelzwiers]

As for your update warning, you can use the --no-update flag to avoid that

Hi, I'm back from my holidays, how's the progress on this issue?
