Hi,<br>
I am analysing a dataset with 180 subjects. When I run
make_average_subjects it crashes, the error message usually being
something like this:<br>
<br>
mghRead: encountered error executing: 'zcat
/space/monkeys/1/home/lmr/subjects/VETSA_test/testAVG/tmp/make_average_vol-tmp/orig-19963b.mgz',frame
-1<br>
<br>
I have tried running it with fewer subjects and it worked with 3, 10
and 73 subjects. Also, it crashes at different points in the processing
stream, so once it crashed at subject # 130, which I removed from the
list of subjects, and then next time it crashed at # 30. My frist guess
was that it is a memory problem. I tried running the top command in a
different terminal at the same time as running make_average_subject
with 2 and 10 subjects, and it seemed to require up to 400m of virtual
memory and 10% of memory, but I couldn't see any difference in memory
demands between running 2 and 10 subjects. This was running with 4G of
physical memory and 2G of swap.<br clear="all"><br>
Is this a known issue? (Couldn't find anything in the mailing list archive..) <br>
<br>
Thank you!<br>-- <br>yours,<br>LMR
