try mri_convert -help. I think it's -ii -ij etc for input i direction.
But the values will of course depend on how the data was collected. If you
have the dicoms around convert from those instead and mri_convert will read
the direction cosines automatically.

Could you please teach me how to specify the direction cosines in the

you need to specify the correct direction cosines in mri_convert. The
problem is that telling left from right posthoc is pretty much impossible
unless you've used something like vitamin E tablets in the scan. This is
why we don't use analyze, unless it comes with an spm-style .mat file
(which does specify the direction cosines)

Hello, after parcellating some brains, I have noticed that the program
"get confused" and label the occipital as frontal and viceversa.
I started with img/hdr images. I suspect that this occurs because of a
"wrong" direction of the original image before doing mri_convert. Is it
true?
How can I solve this?
Thanks,
Wan
