I just tested it and get the same answers in both FSL and SPM.

For voxel indices, remember to subtract 1 for the voxels in SPM as matlab starts from 1 and FSL starts from 0.

Thanks,
This is what I exactly wanted....I did something like:
 fslmeants -i smwc11_1001.nii -c  66.3 45 41  but the output is different from the same voxel location in SPM. Can somebody explain me why? I also did it using mm instead of voxel coordinates.



Hi,

Try: fslmeants

Best,

Eugene

   Can somebody help me with this issue? I was wondering if there is a way to output a single voxel intensity given a specific location in an image?

   Lets say I  do: <Output intensity_COMMAND> <xcoord> <ycoord> <zcoord>  <specific image or images>

   I want to do so using fsl or SPM but for some reason i can't post in the SPM list serv.

   Thanks in advance,
