How to compute CSA from the soft mask?
same procedure-- if you look at the doc of sct_process_segmentation
, it takes soft inputs
Is there a common threshold?
no threshold ("soft" means non-binary)
are CSA voxels area weighted in sum to reflect uncertainty?
the other way around: uncertainty is reflected by soft voxels. Then, sum (used to compute CSA) is weighted
The recently trained contrast agnostic model would be a perfect candidate for this project.

Context
👉 Paper 👉 Documentation
A potential amelioration to the current segmentation method is the use of a soft mask that accounts for partial volume effect during segmentation. This method might improve sensitivity of CSA detection and by consequence improve detection of small atrophies. Additionally csa-atrophy, once T1 and T2 models are ready, could switch to new sct_deepseg,
