I have several regressors in my 3dDeconvolve script and for one of them, many participants have no relevant events. In these cases I've been using the -stim_times option and having a single '*' symbol to indicate 'no stimuli in the given class'.
Despite this I get the following warnings:
*+ WARNING: -stim_times 12 has all times equal to '*' ?!?!
++ -stim_times 12 using GLOBAL times
*+ WARNING: '-stim_times 12' (GLOBAL) has 1 '*' fillers; do you want LOCAL times?
*+ WARNING: !! '-stim_times 12' file '../canonicals/75.6.1D' has no good time values:
I can't find anywhere in your documentation whether the '*' symbol option can only be used with -local_times, but I get this hint from the error message.
If this is the case, is there anyway I can implement a similar option with -global_times? Or, will I have to convert my files from -global_times to local times?
Below is the script I'm using.
