Dear SPMers:
This is regarding high-dimensional warping in SPM5(the latest patch Updates
826). I’m trying to register serially corrected T1W scans using high-
dimensional warping. It’s taken from the same subject using high
resolution T1W(SPGR 1.0x1.0x1.5mm 256x256x100). I’m interested in the
anatomical areas where structures have expanded or shrunk between the two
time points, so I thought it would be useful to try the toolbox.
This is the first time trying this toolbox, and my apology for such a
elementary question, and please correct me if this is not something I
should be doing. I picked high-dimensional warping in the GUI menu, and
selected image from time point A as a reference. In the “moved image”, I
selected an image taken in time point B. Everything else was set to
default values.
The problem is that it hasn’t finished the registration after ~24hrs and
I’m wondering if this is a normal behavior. I’m using a PC(AMD64 1.8GHz 2G
RAM Centos 4_64) with Matlab 7.1.0.183
According to the "top" command, matlab is using 14% of RAM and none of the
swap space is being utilized so I don’t think it’s RAM problem. The CPU
has been 100% the whole time. I appreciate if someone can tell me if it’s
going to take days, weeks, or years to register two scans. Also I’m
attaching the screenshot of what I’ve been seeing for past 24hrs.
Thanks,
Hedok
