To Whom it May Concern:
I am hitting a memory problem in trying to run fMRI-CPCA on a
multi-run/multi-subject data set (specs of data set, machine, and
matlab pasted below). I'm running on an
cpca_8.3.02_Feb_2012 Specifically, I am having an issue with
the creation of GC matrices. I created and normalized the Z
matrix without an issue, and a GZ matrix was created for each
subject in the GZsegs folder, but the program freezes while
creating the first or second GC matrix each time I try to run
analyses. I can't seem to figure out a way to get the program
to pick up where it left off; i.e., it rewrites the GZ matrices
each time I run analysis, as opposed to starting with GC. Is
there any way to start with GC, or are there any other suggestions
that you have for addressing the memory problem? Thanks very
much for your help.
Sincerely,
Steve Wilson
