Generate Spark™ Database is a tool for generating or updating Spark databases. It reads a list of molecules, breaks them into fragments, and stores the fragments into a database file for use within Spark or with the 'Spark Database Search' node.
This node wraps the executable 'sparkdb', which must be installed with a valid license for this node to work. If this is installed in the default location on Windows, then it should be found automatically. Otherwise, you must either set the 'Cresset Home' preference or the CRESSET_HOME environment variable to the base Cresset software install directory. You may also set the 'sparkdb Path' preference or the CRESSET_SPARKDB_EXE environment variable to point directly at the executable itself.
The Generate Spark Database node can be configured to use additional resources to perform calculations. The time taken for the node to run will be drastically reduced if you use the Cresset Engine Broker™. To use this facility either set the 'Cresset Engine Broker' preference or the CRESSET_BROKER environment variable to point to the location of your local Engine Broker. If you do not currently have the Cresset Engine Broker then contact Cresset (firstname.lastname@example.org) for pricing on local and cloud based brokers.
