Well, basically I can filter the file and exlude the interaction that are single.

Code:

a b 0
a c 0 
a f 1 
b a 1 
b a 0 
b c 1 
d f 0  
g h 1 
f d 1

In this case for each row I could check if value in column 1 is present in column 2 and viceversa. If so (present) the interaction is bidirectional.

But still, no ideas in how to apply subsequent filter that is the most important.

I am trying to concatenate the column, sort but really I can't figure out anything.

Best
