no, probably not, but it is something we will need to fix as they should be conseistent. If you run mris_euler_number on e.g. rh.white and rh.inflated and they have the same number of edges/vertices/faces then you are all set.

Hi Bruce, hi Maria, thank you for your suggestions!
However, the message WARN: time for rh.white is older than rh.inflated WARN: lh.rh.sphere.reg is empty/missing WARN: time for lh.white is older than lh.inflated
appears for all subjects I checked.
I tried with the command: recon-all -s <subject> -sd <subjects_dir> -make all
but give me (again for all subjects):
Subject 'subj061': make all make: Nothing to be done for `all'.
Is it something to worry about?
thank you Angela
Hi Angela
- if recon-all has completed successfully there shouldn't be any
topological defects. You can run mris_euler_number on lh.pial and rh.pial. The Euler number for a closed surface with no defects should be 2.
- This means something has been rerun but not to completion. You should
be able to run
recon-all -s <subject> -sd <subjects_dir> -make all
and it will rerun whatever it needs to
cheers Bruce

Hi all, I am running lgi analyses in 5.3 FS version (lion OSX)
one of my subjects failed with a typical message:
lGI for vertex number 39901 of the outer mesh is 1.8067 ... remeasuring lGI value for vertex iV = 40001. It may take a few minutes. WARNING -- Problem for vertex iV = 40001, lGI value is aberrantly high (lGI=42.8793)... ...lGI computation will be stopped. This may be caused by topological defects, check mris_euler_number on the pial surface.
Before running again the command mris_compute_lgi I want to check for the presence of topological defects
I have some questions:
- which is the command line for the command mris_euler_number or -
better
- which are the surface files to control for? (lh.orig, lh.pial,
lh.white, etc...)
- I have performed the command check_subject and in all my subjects
appear this message:
[host-001:~/Desktop/risonanze/studyfree] angelafavaro% check_subject subj061 CHECKING SUBJECT subj061 WARN: time for rh.white is older than rh.inflated WARN: lh.rh.sphere.reg is empty/missing WARN: time for lh.white is older than lh.inflated
What is the problem (if any)?
Thank you for any help
