Hi Joost,

did you try the old one (mris_fix_topology)? Sounds like it failed finding a non-separating loop. What does the unfixed (?h.orig) surface look like? Is something dramatically wrong with it?

cheers, Bruce

Hi,

after a bit more digging i´ve concluded that the orginal topology fixer (mris_fix_topology) failed because: mris_euler_number ../surf/lh.orig

gave

(euler number != 2)

therefore it tries: mris_topo_fixer -mgz -warnings "subjid" lh

which runs for some time and then exits: ERROR: _FindFacePath: could not find path!

any ideas?

• the scan looks (is) crappy due to movement artifacts, which may well be

the cause.

best, -joost

Hi,

using Freesurfer version 4.05 i have a brain that runs through autorecon1 (without errors according to log) but exits with errors during autorecon2. the error given is: "ERROR: _FindFacePath: could not find path!"

other brains in the same set do not give this error message, therefore i assume it must have something to do with the specific brain.

i´ve attached the log-file.

i realize this is little info, let me know what else you need for diagnosis.

thanks, -joost
