Hello dear experts!

I have a question regarding the standard MNI formats - I have my data in the 4mm format (45 x 54 x 45) and in Pick atlas the masks created are in 2mm format (91 x 109 x 91), whereras I need them to be compatible. More precisely, I need the mask to be in the 4mm format (so I want to convert from 2mm to 4mm format), does anyone know how to do that? I couldn't manage in Pick atlas (because I cannot define the format I want anywhere in the procedure, but maybe I missed to notice something?), maybe it is possible to convert in SPM? Any ideas are welcome! :)

Thank you in advance!

Regards,
Sonja
