A tracer that can be used to report the progress of the database generation.
The generated database file is an OpenEye binary file with a header that stores extra information about the database such as, screen type. Each substructure database file is associated with one and only one screen type. The molecules will be pre-processed for that specific type of substructure search. In order to minimize the memory footprints of the dataset at search time, all unessential data will be stripped from the molecules and explicit hydrogens will be suppressed. The search database will store only the following information for each molecule:
the molecular graph (no coordinates)
the molecule title (either user-defined or a unique identifier assigned during database generation)
the screen generated for the molecule
The titles are kept in order to provide an external id for each molecule.
When searching the database, the titles of the matched molecules can be
retrieved by the
If a sorted database is generated (see the
a temporary file will be written into the disk prior to generating the final
sorted database. This two-step process allows to generate database files that
can not be fit into the memory with the size that is limited by the disk
