Dear Jason,
 
Are there any easy reading manual for learning Python or Perl? If we want to transform a two-column table to histogram or in a form of matrix. Can it be done it with Python or Perl?

An example is I have trajectories for several proteins, I extracted angle and distance from the trajectories.
 
Protein A Protein B Protein C
Angle1---Distance1 Angle1---Distance1 Angle1---Distance3
Angle2---Distance3 Angle2---Distance1 Angle2---Distance3
Angle3---Distance3 Angle3---Distance1 Angle3---Distance3
Angle4---Distance2 Angle4---Distance2 Angle4---Distance3
 
Then, I would like to done a table with the following format.
 
              Protein A Protein B Protein C
Angle1 Distance1 Distance1 Distance3
Angle2 Distance3 Distance1 Distance3
Angle3 Distance3 Distance1 Distance3
Angle4 Distance2 Distance2 Distance3
 
Best regards,
Catherine
