How can I determine the contact points in each agglomerate?

Hello everyone,
I want to calculate the collision efficiency. I have the total number of collisions in EDEM.
I also have each agglomerate's info and location. 
For instance, I am aware of the number of primary particles and their positions in each agglomerate.
In order to achieve collision efficiency, I want to calculate the contact point in each agglomerate. 

for example in both cases below(please see the attached picture) there are 3-particle agglomerates but in one of the the contact point is 2 and in the other, it is three.

Would you kindly advise me in this area?

    Hi Fatemeh,


    The contact position is available in EDEM, if you are using EDEMpy you can look at the contacts.getPositions() function for this or in the EDEM Analyst > File > Export results data you can also export the contact Position.

    Thanks for your response Stephen,
    I got the position of contact and collision from the Export results data.
    I thought collision data should be less than contact data and collision data are part of contact position but it is not and the numbers are quite different. (because collision is the contact that takes one-time step)

    Could you please guide me in this field?
