Hi all-

I am looking to see if there is any way to append an additional condition  
to the epoch object in MNE. I want to do this so that I may use the  
mne.epochs.equalize\_event\_counts function for the conditions it already  
holds, in addition to an additional condition.

Thanks for your help,  
Sophie
