Jef,
When adding contrasts via a script, there is a delete setting, for example:
jobs{1}.stats{1}.con.delete = 1;
If set to 1 when new contrasts are added, then only the new contrasts remain
in effect on accessing the model with the RESULTS button. If you set this
flag to 0, perhaps you can then add new contrasts without deleting existing
ones.
See the SPM5 GUI:
Graphics Window/TASKS/Stats/Contrast Manager
Menu item "Delete existing contrasts" (Yes or No)

Now, I have decided to look at 4 new contrast for each of my 10 subjects.
Each time I create the 4 new contrast for the subject, I run them each time
and they are fine. At that time I go on to create the contrast in the next
subject. All seems well until I go back to the first subject. In the spm
design matrix results window, only one of the 4 just created contrast is
there, the other 3 have disappeared. However, when i look in the spm file on
my computer c-drive, it shows all four images created and time stamped. I
have gone so far as to redownload spm5 and just attempted to remodel the
subjects first level spm model. after modeling 2 subjects and creating the 4
contrast, it happened again. I cannot get this to stop. I am trying to
include this analysis on a paper submission for the end of next week.
