Hi, I've looked through the posts but couldn't find a solution to this. I'd be 
really grateful if someone could help,

I'd like to convert a data file of mutual information that is formatted as 
a matrix:

            TF1    TF2    TF3    TF200...
Gene1    0.0    0.2    0.2
Gene2    1.4    0.0    2.8
Gene3    0.3    0.6    1.7
Gene6000....

To a list:

Gene1    TF1    0.0
Gene1    TF2    0.2    
Gene1    TF3    0.2
Gene2    TF1    1.4
Gene2    TF2    0.0
Gene2    TF3    2.8
Gene3    TF1    0.3
Gene3    TF2    0.6
Gene3    TF3    1.7
Gene6000...TF200...etc

The matrix is ~6000X200 in size,

Adam
