Hi,

Have you tried opening the individual images in FSLView (e.g. /Users/MRIuser/fMRI/Homunculus2/Homunculus2.gfeat/cope1.feat/stats/zstat1.nii.gz)?

This will help you to know if there is anything wrong with the FEAT runs.
It will also show you what size the images are and hence what is the matching resolution to use for the masks.

If you do have a mismatch in the resolution of the standard space images, then you can transform between different resolutions following the information here:
http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/MELODIC/FAQ#How_do_I_transform_the_MELODIC_results_from_a_low-resolution_standard_space_to_a_higher-resolution_one.3F

All the best,
Mark

Hi All,

We are trying to do a feat Query at a higher level analysis including 10 subjects; however, every time we try to run the Feat Query, we get the following error message:

hvems-imac:~ MRIuser$ featquery 1 /Users/MRIuser/fMRI/Homunculus2/Homunculus2.gfeat 5 /Users/MRIuser/fMRI/Homunculus2/Homunculus2.gfeat/cope1.feat/stats/zstat1.nii.gz /Users/MRIuser/fMRI/Homunculus2/Homunculus2.gfeat/cope2.feat/stats/zstat1.nii.gz /Users/MRIuser/fMRI/Homunculus2/Homunculus2.gfeat/cope3.feat/stats/zstat1.nii.gz /Users/MRIuser/fMRI/Homunculus2/Homunculus2.gfeat/cope4.feat/stats/zstat1.nii.gz /Users/MRIuser/fMRI/Homunculus2/Homunculus2.gfeat/cope5.feat/stats/zstat1.nii.gz featquery_rOTC_thresh2 -a /Users/MRIuser/fMRI/Homunculus2/MNI152_T1_2mm_brain.nii.gz -t 2.3 -s -b /Users/MRIuser/fMRI/Homunculus2/Localiser_Group/Masks/zstatcomb_rOTC_thr4.9_mask.nii.gz
Error - mask size doesn't match any of the images in the FEAT directory

Our mask will open in fslview on the MNI152-T1-2mm_brain.nii.gz. We tried to do the feat query with the GUI, but we were unable to select our stats and we get something that looks like the attachment. So, we suspect that there is something wrong with the stats rather than with the size of the mask itself.

We were wondering if you have any suggestions on how we could fix this problem.

Best,
