I'm looking for a way to automate surface on volume visualization, to check if the surface reconstruction have been successful on a very large number of subjects. Normally, I would use freeview with -f and -v flags to check and see if it is necessary to edit controls points, etc. 

As an example, one option to automate this process is to use freeview snapshot option and write a script that runs on several hundred subjects and then show all the resulting images in html format.  Running freeview with snapshot option works really good, however, since every freeview run needs X11 there is an overhead here, especially when I'm running on a remote cluster with no X11, which makes running X11 almost impossible. 

I'm wondering whether any one has a better idea for this? 

Thanks

James
