After officially shutting down print production of its famous biochemical pathways posters, Roche made the posters available via a nifty online interface. Unfortunately, this has left people who want a paper copy without a good option. This script will download and assemble the Metabolic Pathways poster from the tiles hosted on their server to give you a large, printable PNG file.

You will need the following requirements:

• Python > 3.5.2
• ImageMagick.

The script will run on OSX and linux machines. Windows was not tested, yet.

Install the requirements in requirements.txt by running

pip install -r requirements.txt

run the script from the command line using

python extract_metabol.py

if python2 is installed, along with python3, make sure to call the script using python3.

python3 extract_metabol.py

This will dump all the raw tiles in images/, assembled layers in assembled/, and the final image finalimg.png in the root directory.

• Specify the zoom level by changing zoomLevel at the beginning of extract_metabol.py.
• If you want to have the original grid, comment out the line that removes grid from the array in the beginning of extract_metabol.py.

• high-quality PNG (13654 x 9571 px)
• low-quality JPEG

• Printable part 2: cellular mechanisms
