The admin interface is visible only to admin users that have complete access to COMMAND>_ functionalities and compendia.
The user menu allow to create, remove and modify users. Moreover, an admin user can assign users to groups and set privileges to them. Group privileges are compendium-specific, i.e. we can for example restrict access only to some compendia and avoid users belonging to a group to see the others. For those compendia we can limit some functionalities, for example we could avoid users to run Python script or import experiments.
From this page a compendium can be created, modified, deleted and initialized. From a technical point of view a compendium is nothing more than a database schema. When an admin user creates a new compendium he will be asked to add all the information necessary to connect to such database.
Once the connection information are saved and a new compendium appear in the grid, it would be possible to initialize it, i.e. to create the database schema.
In this way it is possible to have compendia hosted on different database server. If the database do not exists yet it will be possible to have COMMAND>_ to create it on the fly but you will be asked to provide username and password for a database admin user. Default database admin user is postgres with password postgres.
The Compendium Type section is read-only and at the moment is filled only with gene expression since it is the only type of compendium you are allowed to create. To extend COMMAND>_ and allow other kind of quantitative data to be collected please have a look at COMMAND>_ for developers.
