Hello FSL Experts,
We used probtrackx to generate a connectivity distribution from 1 ROI to multiple ROIs and have fdt_paths.nii.gz and seeds_to_target_{x}.nii.gz files as output files where "x" is the target ROI. We are interested in computing the FA along the tracts from the seed mask(sm) to target ROI(tROI) 1 , sm to tROI 2 until sm to ROI x. We understand that the fdt_paths file has the summed probability in each voxel and seeds_to_target_{x} file doesnot have the path information. Please correct me if I am wrong in my interpretation. Is there a way in FSL to extract only the paths from sm to tROI 1 and use this as a mask to compute FA along this tract? or the only way left is to track again from sm to each tROI1 which is quite demanding in time?
Hoping for some insights.
Thank you.
Cheers,
Virendra
