I'm sorry but there is so much wrong here it is difficult
to know where to begin.

You don't need re since you are not using any regular expressions.

This creates a string called name_in.

And here you search for the string(not regular expression)
"RMSD TABLE" in the return value from name_in()
But name_in is a string, you cannot call a string.

>>> "foo"()
Traceback (most recent call last):
  File "<pyshell#6>", line 1, in <module>
    "foo"()
TypeError: 'str' object is not callable

And this is the only line containing your string so, even if
your code worked, this is the only line you would locate.
It doesn't look very useful...

See my comments above.
