Yes you can do that. The command I've suggested isn't doing a "registration", but interpolation to the resolution of IMAGE_AT_TARGET_RES - which can therefore be any image provided it has the size and resolution you want your final image to have. The "registration" applies the identity transformation with interpolation.

I assume the (72,72,10) is FOV. If yes, you also need to know what is the voxel dimension. If voxel size is the same then simply use fslroi, if not you need to use flirt or fnirt to register them together.

Hi Dear Mr Zhou,

 

Thank you so much for reply. The rsolution of one subject in my study is different to others and I just want to change the resolution of this subject. But I have no AFNI. Do you know to do this in FSL. Looking froward to more instrutions. Thanka  a lot.

Hey Nacy,

Do you want to up-sample the data or just change the field of view. In the later case, fslroi would be the command you are looking for. To change the resolution of the data, AFNI's 3dresample would be a more convenient tool.

Cheers,

Hi dera experts,

 

I want to change the resolution of fMRI in FSL from(72,72,10) to (64,64,10).  Who could tell me how to chang the resolution in command or there is GUI that work. Thanks a lot ahead. I appreciate it greatly.
