How many vertices are on the surface? For nifti you have to reshape the size of the image so that it fits in the nifti format (requires each dim be less than 32k). If the number of vertices has a prime factor that is more than 32k, then you cannot convert it to nifti and use it in another software package (it still works in FreeSurfer, but then you could just use an mgh file then). doug

Hi,
Was there a resolution to this thread on the FreeSurfer mail archive? http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg17886.html
I am having the same issue trying to convert a cortical thickness sig.mgh to a NIfTI file. I want to use the statistically significant area as an ROI in another analysis.
Thanks, Courtney Haswell
