Dear list,
I'm still quite new with SPM99 and I'd like to know the reason for following
thing:
I'm analyzing fMRI-data, two trials (epochs) and baseline. I used box-car
convolved with hrf, no added derivatives. I also high-pass filtered my data.
Nothing unclear yet, SPM99 calculated everything very nicely. Then I noticed
it had created also the following files: beta_*.mat, mask.mat, ResMS.mat,
RPV.mat. Also when I created contrasts and looked at the results SPM99
created automatically spmT_*.mat and con_*.mat -files. I haven't had these
files ever before when analyzing fMRI-data, and today I first analyzed the
same kind of paradigm and got no .mat-files. Then suddenly these appeared.
What is the function of these .mat-files and why I suddenly got these? I did
move all earlier files away from the SPM99 working directory so that can't
be the reason either.
Can anyone explain this to me?
Thank You!
