all of our data is transformed to be 256^3 before processing unless you specify otherwise. If you want to undo it, you can use the -rl <volume name> switch in mri_convert ("reslice like"). If it is an aseg volume make sure that you specify the resample type as nearest neighbor with -rt nearest
Note also that all of our binaries can write nifti (including mri_binarize) cheers Bruce

Dear Experts,I've made some volumes from aseg.mgz using mri_binarize and then used mri_convert to make nii files. But when i open these files using Mricro i see the original dimension of the image has changed ( 181,217,181 to 256,256,256). I have no idea what the problem is. I'd appreciate your help. Many thanks in advance Best
