Dear Virgil,
I'm a student in Tononi lab and I've started to use your code for calculating 
Phi for some simple 
systems. Unfortunately, I need some more operations (especially AND for 3 and 4 
inputs, XOR for 
three inputs). I've therefore slightly modified your code to allow such 
operations, and changed 
the format of circuit.
Here's the changes I've made:

In t_consc.h:
Line 26, struct t_transformation:        
int A, B, C, D;

-----------------------------------------------------------
In t_consc.cpp:
Line 1097 and following, void t_consciousness::load_transformations: 
//READIN CIRCUIT NETWORK
    else if( this->networktype == "circuit" )
    {
        t_transformation t;
        int I,A,B,C,D;
        char op;
        while(!(feof(f))){
            fscanf(f,"%i    =   %c  ",&I,&op);  //%i    %i  %i  %i\n,&I,&op,&A,&B,&C,&D);
//          t.A=(unsigned char)A;
//          t.B=(unsigned char)B;
            switch(op){
                case 'A':
                case 'O':
                case 'X':
                    fscanf(f,"%i    %i\n",&A,&B);
                    t.A=A;
                    t.B=B;
                    break;
                case 'E':
                case 'N':
                    fscanf(f,"%i\n",&A);
                    t.A=A;
                    break;
                case 'S':
                case 'C':
                    fscanf(f,"%i    %i  %i\n",&A,&B,&C);
                    t.A=A;
                    t.B=B;
                    t.C=C;
                    break;
                case 'D':
                    fscanf(f,"%i    %i  %i  %i\n",&A,&B,&C,&D);
                    t.A=A;
                    t.B=B;
                    t.C=C;
                    t.D=D;
                    break;
            }
            switch(op){
                case 'A':t.operation=0; break; //AND
                case 'O':t.operation=1; break; //OR
                case 'X':t.operation=2; break; //XOR
                case 'E':t.operation=3; break; //COPY
                case 'N':t.operation=4; break; //NOT
                case 'S':t.operation=5; break; //AND3
                case 'C':t.operation=6; break; //XOR3
                case 'D':t.operation=7; break; //AND4
            }
            transformations.push_back(t);
        }

Let me know if you think these changes could be applied to you program.
Thanks a lot.
Best regards

I've been using an older version of the code for some time, always getting 
correct results (see Issue 
1 for some modifications I made). The latest version, however, seems to give 
uncorrect results when 
using wire perturbation and Tononi normalization (I can calculate Phi values in 
this way with 
different programs). I tested a simple AND gate with 2 inputs, running do.py.


Moreover, setting the flag for printing Phi values for each distinct state 
seems to give some issues 
as, for some systems, the program exits before completion.

Thanks,

Umberto
