Hi Kim
are you really sure that you want to use analyze format? I doesn't keep
track of the direction cosines properly so once you go to it it is hard to
know left from right. SPM should be fine with nifti. In any case
conversion should be something like:
mri_convert file.mgz file.nii
or
mri_convert file.mgz file.img
although again, I wouldn't recommend using analyze
cheers

Dear expert,
I'd like to convert .mgz (or .nii) file to .hdr file (.hdr and .img) to use

I tried to convert the file using "mri_convert". But, there were the error
messages below.
Please, let me know how to onvert .mgz (or .nii) file to .hdr file (.hdr and
