I was wondering if I could clarify measuring the mean FA within a ROI.
I have drawn some masks in FSLview using the MN152 and all_FA images
as guidelines. I'm interested in the mean FA within those masks in
each individual.
From the list, I gathered that the following should do what I wanted:
fslmeants -i all_FA -m my_mask -o output.txt
The output of this was a list of values, corresponding to each
participant. I presume they're the mean scaled FA for the ROI in a
participant.
Does this process sound okay?
Secondly, is there a way of determining the exact order of
participants within the all_FA? Would the index.html in FAi/slicedir
do this?
Thanks
Suzanna
