Chanel Event function

Hi all, 

I have a dataset with two channels: (1) a signal which has boolean values (1/0) and (2) time. I want to eliminate the noise of this signal, so I mean giving a value of 0 to the signals which last less than 2 minutes. I guess that first of all, I need to calculate the delta X when Y=1 and once I have that I can eliminate the smallest values. I was recommended in a previous post to use the Event Search function for calculating this in diadem 2015, but I do not know how to use it in a script. 

Thanks
