Hello,
I have a question regarding the output files from the ccops command within FSL.
I first ran ProbtrackX specifying matrix option 2 in order to obtain
an estimate of streamlines connecting brain region A to brain region
B. I then ran the ccops command to cluster voxels in region B based on
connectivity patterns from region A. If I am not mistaken, these
cluster masks are stored in the file
reord_mask_regionB_kmeans_4.nii.gz.
An important question is now from which voxels do these clusters
originate? Is that information stored in the file
tract_space_propagated_regionA_kmeans_4.nii.gz? It appears that both
files have values according to the number of kmeans clusters that I
specified (i.e. 4). Do these numbers correspond across these files?
That is, does cluster 1 in the reord_mask_regionB_kmeans_4.nii.gz
stems from voxels with the value 1 in the
tract_space_propagated_regionA_kmeans_4.nii.gz?
Any help would be greatly appreciated.
Thanks,
Cornelia
