Is there any way to safely delete contrasts in SPM5?
Naively, I would just
load SPM
then do
SPM.xCon = [];
then
save SPM SPM
but I'm a little leary of this because (a) I'm new to SPM5, (b) there's
this new stuff using matlab classes.(*)
(*) One weirdness (here, SPM.mat is after estimating a second level model,
but before running any second level contrasts):
- If I load SPM.mat without putting SPM5 in my matlab path, I get
an "unknown object class error." If I go ahead and type
save SPM SPM
the resulting file is much smaller.
- If I have SPM5 in the matlab path, and then load SPM, I no longer get
the unknown class error. But if I save SPM to SPM.mat, it's still much
smaller than it was before I loaded it.
