Followed instructions. Right up to this point:

$ ./preprocess.sh ~/Desktop/newreads/Gumsley2017PNAS.pdf

./preprocess.sh: line 15: gs: command not found
Academic tradition requires you to cite works you base your article on.
If you use programs that use GNU Parallel to process data for an article in a
scientific publication, please cite:

This helps funding further development; AND IT WON'T COST YOU A CENT.
If you pay 10000 EUR you should feel free to use GNU Parallel without citing.

To silence this citation notice: run 'parallel --citation' once.

Running this command does result in creation of docs/document_name with the original PDF and two empty directories png and tesseract.

Pg database and tables created but empty.

Note too that there can be no spaces in the path and file names if this is going to work.

Starting from a fresh virtual env I was able to get it to work:

virtualenv env
source env/bin/activate
pip install -r requirements.txt 
python -c "import PIL"
