    with open(o.qdec, 'rb') as f:

            ^

SyntaxError: invalid syntax

it appears each time I run aparcstats2table, even when I write: 

aparcstats2table --help

I have changed the environment variables in order to run the 5.1 version, and it works as always.

What else should I check? 

thanks!
