automatic counting of spontaneous calcium activity transient peak/min or sec

Dear Friends,

I am rather new to the use of Igor, so this may be a very nave question. I would appreciate advice on creating an efficient procedure for implementing it.

I am recording spontaneous calcium activity and I would like to count spontaneous calcium activity transient peak/min or sec. I would like to count it automatically like mini analysis did for patch clamp data. Here I would like to count it for several cells traces at a time and I was wondering if there is procedure to do it using Igor.

Many thanks for your help,
Manoj
