Error when running a folder of .eaf files while specifying no

I'm attempting to parse the ELAN version of NCSLGR (ASL) corpus, as found at http://asl.cs.depaul.edu/corpus/index.html

However, I encounter an error where the script seems to want to generate a folder inside a text file

python elan_processor.py -i ~/Documents/corpora/NCSLGR/elanBUcorpus/ -o ~/Documents/corpora/NCSLGR/test/ --video_mode 4
