Dear Yuko You may try using fslswapdim (from fsl) which is a very handy function. Here's how to do it from Matlab command line window, inside an .m file, or if you prefer to use the terminal: system([' fsl4.1-fslswapdim_exe ' input_file ' y z -x ' output_file]); You may choose the orientation by varying (y z -x) to the intended orientation...
