Hi all,
I have a question regarding the use of realignment parameters as
regressors for two replicate sessions in SPM2. I'm dealing with two
sets of fMRI data from two sessions that have exactly the same
conditions. In the preprocessing steps I treat the sessions as
replications and, after realignment, get two separate rp_*.txt files
containing the realignment parameters. However, when I specify my model
design, under 'Other Regressors' I'm only prompted to specify regressors
for session 1. How can I do the same for session 2? I'd like to
analyze the two sessions together if possible, generating only a singe
SPM.mat file.
Thanks,
Daron
