sorry, i meant to say include the --no-aseg flag with make_average_volume (make_average_subject is just a wrapper script that calls make_average_volume and make_average_surface).

Hi:

Thank you for your replies. But how I can including the flag? According to wiki there is no such optional argument in mark_average_subject, and adding "--no-aseg" did not work. Can you advise me in more detail?

Thank you for your kindness help.

try including the -no-aseg flag with make_average_subject. this out-of-memory error is a known issue, that only has this work-around.

Dear freesurfer expertise:

When I perform the make_average_subject to obtain the custom average template, I encountered following error message in make_average_volume step:

---

Loading mask /usr/local/freesurfer/subjects/avgsubject/mri/brainmask.mgz ninput = 64 Chcking inputs Checking 0 /usr/local/... ... Checking 63 /usr/local/... nframestot = 64 Allocing output MRIalloc(256, 256, 256): could not allocate 262144 bytes for 11578 slice

Cannot allocate memory ERROR: make_average_volume

Does that mean insufficient memory? or something wrong within my data? All subjects finished recon-all step without error and the "make_average_surface" step also finished without any error.

Thank you for any advise.
