Add information regarding possible other reasons for "No 'metadata_' keys in config..." error #5

Closed svenwillger closed 2 years ago

svenwillger commented 2 years ago

The error for "if not refconmd" would also be thrown if the config file is missing the key "metadata" or refcon_md is empty for another reason. This could be clarified if necessary.

what about this one?

svenwillger commented 2 years ago

Since the error could only occur if we introduced it or something is broken that causes an empty 'refcon_md' I added a sentence to contact the developers if the user is sure they did everything right.

raise ValueError(
            "\nPotential user error:\n"
            "No 'metadata_' keys found in config. Did you forget to load a reference container config?\n"
            "You must specify the container configuration files via Snakemake's '--configfiles' option.\n\n"
            "If you are sure the container configuration file(s) with the 'metadata_' key word is/are present\n please contact the developers.\n\n"
        )

The commit comment is "Update to resolve issue #5"
