The model code seems not to recognize "YES" as true, even though it doesn't give an error when a BOOL is set to YES or NO.
I think the best solution is just require all boolean variables to have values of 0 or 1.
However:
Observer.Setup has a variable takeRasterPictures that appears boolean BUT it's described in the doc. as "text" and takes values of YES or NO. Leave it be, I guess.
Experiment.Setup booleans can be YES, NO, 0, 1.
I see that if you are in the Experiment menu and add a boolean model parameter (e.g., appendFiles) to an experiment, the GUI puts in default values of "0". That should work.
