CiftiPy - Better python support for cifti files #26

Open pvandyken opened 1 year ago

pvandyken commented 1 year ago

Title

CiftiPy

Short description and the goals for the OHBM BrainHack

cifti is a neuroimaging file format that flexibly stores vertex and voxel data in the same file. It's the format of choice in the HCP processing pipelines for storing surface maps, but can also be used for cortical parcellations, brain segmentations, structural and functional connectomes, and many other applications.

Currently, there isn't an easy way to handle this format in python. Nibabel has support, but the interface is unintuitive and bulky.

CiftiPy will be a wrapper around nibabel offering a convenient, numpy-based interface for accessing and manipulating cifti files. It will offer convenient methods for indexing cifti files by data-type, structure, and hemisphere, be easily and transparently viewed in an REPL (like pandas or xarray), and offer methods for common tasks.

Goals

No code has been written yet, but we have a fairly clear plan for the API. The goal will be to implement, test, and document the core interfaces.

Long term

We are prioritizing robustness over number of features, so we're purposefully trying to keep the scope as small as possible. If we get a good cifti interface built, however, it could in principle be extended to support other neuroimaging file types (gifti, nifti), resulting in a generalized, user-friendly nibabel wrapper.

Hi @ufangYang, sorry, I haven't had time to put into this. Can you just put this modified version of our pitch:

Also, there was only space for one author in the form, not sure how to put my co-authors:
