The Entrypoint

After writing a metadata file, the last step is to use your metadata file to generate an entrypoint. In the top level of your workflow directory, run the following:

latch snakmmake generate-entrypoint .

This will create a file in a folder called wf called entrypoint.py, containing an autogenerated Latch SDK workflow that subprocesses Snakemake with your parameters injected appropriately. Since this is a Latch SDK workflow, you can modify however you like to add, e.g. pre/post-processing steps.

Note that if you would like to change the interface of your workflow, you need to update the metadata file and then regenerate your entrypoint.
