Hi Ali

mris_convert converts surface while mri_convert converts volumes (in general these prefixes hold across all our binaries – the mris_ ones do surfaces and the mri_ ones do volumes).

To convert a patch you need to tell mris_convert that it is a patch and not a complete surface by giving the -p flag

Cheers

Hi all, 

I'm trying to use mris_convert and can't get it to work.

current command I'm using:

mris_convert lh.full.flat.patch.3D lh.full.flat.patch.3D.asc

also can't seem to find the difference between mris convert and mri convert so don't know if I should be using that instead.

any advice would be appreciated

thanks, 

Ali
