# Uploading and Importing URL Core Configuration ## Uploading from a Core Configuration File TrialGrid allows a Core Configuration file downloaded from Rave to be uploaded. This is a quick way to set the Core Configuration options which TrialGrid requires. These are: - Deviation Classes and Codes - EDC Roles - Marking Groups - Review Groups - Subject Status Uploading a Core Configuration file *overwrites* the existing settings for each worksheet found in the file. If the worksheet corresponditing to a configuration option (e.g. Review Groups) is not found then those settings are ignored and are left unchanged. ## Importing from another URL You may also import Core Configuration settings from another URL set up within TrialGrid. Importing from another URL also *overwrites* the existing settings for the Core Configuration.
