Local and Shared Repository

LigandScout uses a “ two-level ” file storing strategy, the Shared Repository (or Central Repository) and the Local Repository. If a PDB code is entered in the PDB 4-letter code field of the PDB Panel , LigandScout tries to find the associated files in the first level Local Repository. If unsuccessful, LigandScout will check the Shared Repository which represents the second level. The Shared Repository is usually installed at a central location and every licensee can take advantage of it by specifying the correct path to this repository in Preferences/Program & Network Settings . As the second level repository is intended to be shared among all licensed users, it is not modifiable using LigandScout (the only exception is if a new repository is installed to be the new Shared Repository). Hence, there is the first level repository which contains all of the changes that were performed on a structure locally (if the user decides to save them). Also, recently downloaded and interpreted PDB structures will be stored there for faster retrieval later on.

Handling the Repository

Save to Repository

You can store changes to your current active site to the Local Repository with File > Save to Repository (CTRL+S). If you do not use this command and you load new data or quit LigandScout, a Save changes dialog reminds you to store or discard the modified data.

Importing a Repository

The Import Repository command (CTRL+ALT+SHIFT+I) in the File > Repository menu allows you to install a PDB repository.

Exporting a Repository

The Export Repository command (CTRL+ALT+SHIFT+E) in the File > Repository menu enables the export of your PDB data storage. To allow sharing your Local and Shared Repository you can choose to store it as a single compressed archive. Choose Local Repository for your local storage. If the repository is located on a server and is to be shared with other users, select Shared Repository . Make sure that you have writing privilege for this location. The path to your Shared Repository is specified in the Preferences/Program & Network Settings whereas the Local Repository will be managed by LigandScout.

Clearing the Local Repository

The Clear Local Repository command (CTRL+ALT+SHIFT+C) in the File > Repository menu erases the local PDB data storage. All changes and modifications will be lost if the Local Repository is cleared.
