The grad_unwarp_tables directory is not distributed with the public release of freesurfer, as the files are under Siemens license to the NMR Center only. So I suppose you could check with Siemens to see if they can supply you with those data tables for your scanner.

Hello,

We used to run:

grad_unwarp with matlab invoked with -nodisplay option. The version information on this file is:

version: Version for distribution, 1.0, author: SC----------- id: id9/01 13:34:11

I see that Freesurfer 5.1 has a grad_unwarp script, which I can modify to invoke matlab with -nodisplay, however, I dont see any sub-folder grad_unwarp_tables in FREESURFER_HOME. Where do I get these tables from? Am I missing some installation option?
