Hi Vincent,

Can you show us a snippet of the file output?  I'm not immediately seeing
anything particular with your debugging output statements:

    myfile.write('base ' + str(current_base) + ' mutated to ')
    myfile.write(str(a_genome[current_base]) + '\n')

Like the computer, I don't yet understand what the problem is.  *grin*


If you can point us at the output that looks weird to you, and tell us
what you expected to see instead and why, that will help us a lot to
better understand the situation.



Best of wishes!
