In the Free package, the maximum number of user-generated collections is 20 and the maximum number of entries stored in a single, user-generated collection is 10,000. In practice, this means that in screening workflows with multiple steps, only the resulting collection’s size is limited, all molecules that satisfy the preceding workflow steps’ criteria are processed.
Users who subscribe to any for-fee packages can have 1,000 collections simultaneously and can have more than 10,000 entries in each of their collections.
If you reach your maximum allowed number of collections, you will need to (export and) delete some of your older collections to get enough storage for your new results.
