Hello, 

I am wondering if it is possible to completely bypass the segmentation step without having to provide mask files for WM/GM/CSF. Basically, I need to skip all preprocessing and denoising. I have extracted seed time courses outside of CONN, and I want to run the analysis on a smaller part of the brain that has been isolated and aligned separately. The built-in segmentation can't cope with this partial brain coverage, and I can't (and don't want to) make segmentation masks for this part of the brain. 

Before giving up I wanted to check with you in case I missed something obvious :) 

Many thanks!
