Are you sure the problem isn't simply that, even though your machine is 64-bit, the FreeSurfer MacIntel distribution is only 32-bit? Cheers, Steve.

Hi bruce,
Thanks for looking into my 'maximumnumber?' problem. Good to hear
that you
have run in on 300+, at least I know it should be possible and
there is no
fixed maximum number.
Hope to hear from you,
thanks, Martijn

Hi Martijn,
it looks like we have a memory leak. We'll look into it and get
back to
you. I'm surprised you don't get past 253 with 16G of ram
though. I've
run it on 300 or so.

Dear Freesurfer-list,
I'm trying to construct an average group surface map using 'make_average_subject'. My group consists of a rather large
number of
subjects, around 400 subjects.
Unfortunately, running 'make_average_subject' gives an error when
processing
subject 253, saying it has an 'mgh reading error' on the '
T1.mgz'.
I checked that the involved files are all oke. In addition, I
have run
'make_average_subject' several times with different group
lists, but
every
time it stops at subject 253.
I'm using an Intel MacPro with 16 GB of system memory, and
there is
plenty
of free memory when it runs.
Is there a maximum set on the number of subjects you can use in 'make_average_subject'? Can I reset this value?
Yours sincerely,
Martijn van den Heuvel
