No errors with sending the command to shell.

I did get some errors though with a few runs of it in a terminal here is an example.

ValueError: could not convert string to float: bj@bj-HP-Pavilion-dv5- Notebook-PC:~/Desktop/tunetof$ python scl2pd.py stiltnerphihr16.scl Traceback (most recent call last): File "scl2pd.py", line 69, in <module> tab = convert_scala(file) File "scl2pd.py", line 58, in convert_scala tab.append(ratio2float(l)) File "scl2pd.py", line 21, in ratio2float return float(r[0]) / float(r[1]) ValueError: could not convert string to float:
