can you look in the surf dir and see if lh.occip.patch.3d exists? On Tue, 31 Oct 2017, Patricia Stefancin wrote:

In response to my previous question, the command line I was using was mris_flatten -1 -w 0 -distances 20 7 lh.occip.patch.3d lh.occip.patch.flat

When I run this, the terminal output reads :

lh.occip.patch.3d no such file or directory.

I followed all the steps to create the patch, and saved the file with tksurfer. I don't know what could be going on.
