External Email - Use Caution        

Hi,

I am testing version

freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c
against version
freesurfer-linux-centos7_x86_64-7.1.0-20200511-813297b
My system is:
Debian GNU/Linux 8.9 (jessie)

I tried to merge labels corresponding the same network into one, i.e. I have now only 11 labels, comprising almost all cortical surface. This seems to spare a bit RAM, but still it required approx. 38 GB RAM to load all labels.

Please also let us know the version of the OS you are comparing running both the 6.0.0 and 7.1.0 release on.

Dear experts,

I want to use freeview for viewing Gordon surface labels on inflated surface with custom coloring. I am using commandline like

freeview -viewport 3d -f $SUBJECTS_DIR/fsaverage/lh.inflated:label=L_Auditory_10.label:label_color=255,191,0:label=L_Auditory_11.label:label_color=255,140,0....etc (the commandline contains 161 labels)

I observe that freeview in version 7.1.0 consumes much more RAM than in version 6.0, using identical command line. 
The difference is enormous: While in version 6.0 freeview consumes 1.5 GB RAM to successfully display all labels, freeview in version 7.1.0 consumes all memory available on the server (32 GB RAM) while only about 30 labels are actually loaded (then server start to swap and I am forced to kill freeview process).

Are you aware of such behaviour?

Regards,

Antonin Skoch
