Description

I haven't had the time to sit down and really understand this, but nipy has STC implemented as part of realign4d. It uses affine transforms, so I suspect we can find a compact serializable representation of STC for nitransforms.

https://github.com/nipy/nipy/blob/d16d268938dcd5c15748ca051532c21f57cf8a22/nipy/algorithms/registration/groupwise_registration.py

This is brought up in the context of attempting to reduce the outputs of preprocessing to a minimum while preserving flexibility for downstream uses. In the absence of an STC transform, the ST-corrected BOLD series would be a required output, if calculated.

Research direction

Start by reading the linked nipy file, algorithms/registration/groupwise_registration.py, to understand how STC is represented with affine transforms. Done means establishing and implementing a compact serializable STC representation for nitransforms, while clarifying whether the ST-corrected BOLD series remains a required output.
