Dear SPMers,
I’m estimating a very simple model (one subject, four sessions, each
composed by six conditions and by 138 scans), but I’m quite surprised by
the slowness of the process: only 45% after almost 8 hours!!
I’m using Spm99,working on Matlab R12 under Windows XP, on a laptop with
752 Mb of ddr Ram and an Athlon Xp 2000+ processor.
I’ve already estimated similar models on a desktop Pentium 4 2GHZ, with 512
Mb Ram on Matlab 6 under linux (Slaqware), and the whole process took not
more than 20/30 minutes…
So I was wondering if the problem is in the hardware (is a laptop so much
slower than a desktop?) or in the operating system (is matlab/Spm so much
slower under Windows XP than under Linux?) (or perhaps a combination of the
two?).
Thanks in advance for any suggestion,
Nick
