Im working on a batch processing command (below), and am running into an error having to do with setting up the conditions:

"testIndex exceeds the number of array elements (2).

Error in conn_batch (line 1131)
t1=batch.Setup.conditions.onsets{nconditions}{isub}{nses};
Error in CONNsmDenoiseMNIvol (line 58)"

If I run this without the code related to conditions, I can confirm in the GUI that the number of subjects and sessions are correct, and that the functionals and structural are getting loaded.

clear batch;
batch.filename=fullfile(output_dir,'conn.mat');
