Possible explanation

This error happens when the data bases cannot be loaded into the tool and the main cause might be;

  1. Not providing the correct path to the models folder
  2. providing the wrong pattern to match the models in the directory

Possible solution

  • Ensure you provide the correct path to –models_folder argument
  • Ensure the patterns are provided correctly. In the example below only models which start with en_Brain_ will be selected.

    –models_name_pattern “en_(.*).db”
    –models_name_filter “en_Brain_(.*).db”
