CIFTI parcellated ptseries.nii files, throwing an error "file_array objects can not be permuted."

Hi, I had issues with PALM has an issue when processing CIFTI parcellated ptseries.nii files, throwing an error "file_array objects can not be permuted."

The FSL mailing list has a post about this error and how to address it (needs to modify one of PALM's file): https://www.jiscmail.ac.uk/cgi-bin/wa-jisc.exe?A2=ind1812&L=FSL&D=0&P=40415. Even though this post is from Dec 2018, the most recent version of PALM (PALM alpha116) still has this issue.

Is the solution proposed in the FSL post still valid? If implemented, are there any possible downstream issues when using PALM with other types of input files?

Hi @estephanmoana, thanks for the message. I think the reason why this wasn't fixed back then was that I didn't want PALM I/O functions to diverge from Guillaume Flandin code, which is also used in SPM.

@gllmflndn if this has been changed in the current version, perhaps it'd be time to update I/O in PALM? What would you suggest?

Thanks!
