What if I have created a surface model and it looks bad?
Sometimes the cortical surface model created by FreeSurfer contains large errors. For instance, in this picture, part of the pia-arachnoid-dura has been classified as part of the cortex. To fix this error, AFNI's "draw dataset" plug-in can be used to try and fix the problem. Change the {$ec}_anatavg+orig dataset directly. (If something goes wrong, a new one can be made from the original T1s). Set the drawing value to 0 and pick a paintbrush style. Identify the offending voxels and paint them in black. Then, rerun the surface creation routine.
