Hello,
here's a question re fslmaths, but other suggestions on how to achieve
the following are also most welcome.
I need to obtain the upper n number of rank-ordered voxels in an image -
a grey matter PVE map. The n of voxels for each patient should be
constant, and should be the ones with the greatest pve_1 value. The -thr
option won't do because my images are from (severely) brain damaged
patients, and in native space, so -thr will almost certainly give me a
variable number of voxels for each subject.
Many thanks
Angie Kehagia
