0100,0100,0100{PRIVATE}Courier NewDear colleagues,
I performed an event related fMRI experiment
and analysed it with and without slice timing.
The analysis without slice timing worked out
well. After slice timing I run into an out of
memory error, when I estimate the model. The
only differences between the two analysis is
that I added the slice timing step to the
preprocessing.
The image parameters are the following:
315 image volumes, 31 slices
initial matrix size 64x64.
The error occurs after 87 % completions of the
model estimation.
The used hardware:
* Intel Pentium II Celeron 400 MHz
* 578 MB RAM
* 55 GB IBM Hard disk
* 10 GB Swap Space (I raised swap space as
recommended in your help line, but it does not
work)
SPM version: SPM99
Does anybody have an idea how to solve this
problem?
Sincerely yours,
Lukas
