Custom atlases in ASLPrep

Is there the option to specify custom atlases in ASLPrep?

That’s not currently supported behavior, but if the atlases are in the same space as your chosen output-space, you can use something like Nilearn’s NiftiLabelsMasker.

If this is a feature you think we should add, please open an issue in the ASLPrep repo requesting it: Issues · PennLINC/aslprep · GitHub. I can’t guarantee that we’ll implement it, but we will definitely discuss it in the issue.
