Hi all, I would be very grateful of any advice for the problem below with e-TIV.
I have another problem with the longitudinal streaming (it is the first time I use it). I am running the .base and .long procedure in subjects with only one measure to include them in a mixed liner model analysis (as suggested in the wiki). I run the following commands: recon-all -base template100 -tp subj025 -all recon-all -long subj025 template100 -all However at the second command line an error occur (attached is the log): BEGIN failed--compilation aborted at /Applications/freesurfer/mni/bin/nu_correct line 37. ERROR: nu_correct Darwin iMac-di-Angela.local 11.4.2 Darwin Kernel Version 11.4.2: Thu Aug 23 16:25:48 PDT 2012; root:xnu-1699.32.7~1/RELEASE_X86_64 x86_64 recon-all -s subj025.long.template100 exited with ERRORS Which is my mistake? I looked for a solution in the mailing list, but I did not find an answer. Thank you for any help!
