Dear Freesurfer experts,

I'm trying to load the flat surface that I created with this command line:

mris_flatten -w 10 lh.full.patch.3d lh.full.flat.patch.3d

I tried loading the patch inside freeview but I got this error message:

[francesca@GIOVE surf]$ tksurferfv sub01_mprage lh inflated
freeview -f /home/francesca/freesurfer/subjects/sub01_mprage/surf/lh.inflated:curvature=/home/francesca/freesurfer/subjects/sub01_mprage/surf/lh.curv -viewport 3d
ASSERTION FAILED: /home/rd521/space_freesurfer/build/docker_centos8/trunk/rd521-7.2.0/utils/mrisurf_metricProperties.cpp:4248 mris->dist_nsize == 0
ASSERTION FAILED: /home/rd521/space_freesurfer/build/docker_centos8/trunk/rd521-7.2.0/utils/mrisurf_metricProperties.cpp:4248 mris->dist_nsize == 0
Errore di accesso al segmento di memoria (creato file core)

And I tried to run this command line but nothing happened:

[francesca@GIOVE surf]$freeview -f lh.inflated:patch=lh.full.flat.patch.3d

Thank you, 

Francesca
