Hello,
I am trying to estimate a rather large (and perhaps crazy) 2nd level
model, with around 5000 contrast images.
I should have managed to free up enough RAM in my XP 32bit system (RAM
defrag + 3 Gb Windows boot switch + startup in -nojvm mode): I do no get
the memory error when the factorial design specification starts.
However, the computation appears to hang: after 10 hours of full-load
CPU the Matlab process appears to have read or written nothing more than
what it did at the beginning of the factorial design specification
phase. Is it possible to estimate roughly how much time this phase would
take, AKA, at which point should I start suspecting a problem with the
computations, if any? I am finding, for instance, that the sort
rows/columns loop in spm_get_vs alone takes around 190 minutes.
Thanks,
Bruno
