hello,
I am trying to simply create new contrast on an already existing spm first level model. my orginal model has 16 contrast with associated con images. 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.
I am desparate and would great appreciate any ideas as to what could be going on. Thank you in advance for any and all suggestions.
thank you
jef
