constructing an adjacency list from incidence matrix

I have a directed graph with an incidence matrix like this:

AP=[1,0,0,0,0,0,0,0;-1,0,1,1,1,0,0,0;0,0,-1,0,0,1,0,0;0,0,0,-1,0,0,0,0;0,0,0,0,-1,0,0,0;0,0,0,0,0,-1,0,0]

AP =

     1     0     0     0     0     0     0     0
    -1     0     1     1     1     0     0     0
     0     0    -1     0     0     1     0     0
     0     0     0    -1     0     0     0     0
     0     0     0     0    -1     0     0     0
     0     0     0     0     0    -1     0     0

How can I construct an adjacency list with this information? Thank you!
