Since it is corrupted in your e-mail below, I will reproduce what I said:
"fslstats –M * fslstats –V is the mean number of connections times the total number of voxels giving the total number of connections" in a seeds_to_targets result.
I wouldn't recommend comparing this number across subjects, but you can compare different structures within a subject. I'm not sure how you would normalize this either across subjects.
Peace,
Matt.

Hi Stam,

what i was wondering is that what exactly does the "total number of connections" mean here.
for seed_to_target:
"(fslstats –M)* (fslstats –V)=total number of connections"
as far as i understand, the waytotal is the (number of streamlines sent per voxel)*(size of the seed mask)
If I normalize the (fslstats –M)* (fslstats –V) by waytotal, would it then make sense for between subject comparison?
Thank you again
Natalia
