relation_to_json.py error

[matt496]

Hi, I have an error message when I run "relation_to_json.py":

"Traceback (most recent call last):
File "relations_to_json.py", line 87, in
relations_to_json(config)
File "relations_to_json.py", line 24, in relations_to_json
with open(input_txt_file, 'r') as f:
OSError: [Errno 22] Invalid argument: 'relations.txt\'"

I didn't have this problem before but now I don't know what to do, maybe someone can convert my txt for me?
