Error using conn_module for denoising only

I'm trying to use the functional_regression and functional_bandpass steps using conn_module on resting state fMRI data. I successfully smoothed the preprocessed data using conn_module before trying to denoise. 

After using conn_module with the .cfg option within MATLAB I received the following error messages that I have not been able to troubleshoot.

I also attached the conn_denoise_only.cfg file
