Hello SPM helpers,
We did some preliminary analyses of PET O-15 data (5 subjects) some
time back using SPM96 implemented under Unix and Matlab 4.2. Now we have
collected more data (11 subjects) and we have installed SPM99 on Windows NT
with Matlab 5.3.
When re-analyzing the data (including realignment and normalization
within SPM99) we seem to be getting quite different results. I believe the
difference is at least partly due to SPM99 making the correction for time
effects within session (scan number).
I would like to compare the SPM96 and SPM99 analysis on the same
datafiles, but we no longer have access to the Unix installation of SPM96.
According to the SPM HELP files, it should be possible to access the SPM96
format for setting up the design matrix. However I can't find the SPM96
options on the menu for PET/SPECT analysis. Can you please tell me how to
implement an SPM96 analysis for PET under SPM99?
Thank you in advance,
Ruth Reinsel
