RE: Warning: Divide by zero.
Because you specified Weighted as 0, and your events are non-zero
duration,
then the program treats the data as a block design. This just means that
when it averages across runs, each run gets an equal weighting - rather
than weighting based on the number of trials.
I will fix this piece of code to avoid the warning message in the future.
Also, RT as a PM doesn't make much sense because RT should change the
duration of the neural activity rather than just changing the amplitude.
In the future, you don't need to specify the run # in the condition name as
each run # is prepended to the task name in the GLM.
