Good Day,
I am trying to run gPPI on a model that contains no regular non-parametric and parametric regressors and I get this error:
"Estimation Failed
Warning: Missing conditions!!! Invalid Contrast
Invalid Contrast
PPI Contrasts were not estimated for some reason."
I tried running the same analysis on another model that does not have parametric regressors and it appears to be running.
Is there a way that I can code the script to allow for parametric regressors in the model, or do I need to rerun my model with only non-parametric trial types/conditions?
Thanks!
