Miscellaneous#

Here we briefly describe subdirectories and their files that are not part of the main dataset but are used in the dataset processing pipeline. These files should be considered intermediate products and are not intended to be used directly, only for development purposes.

Each file is a CSV with a single column: pdb_id.
