OCHEM allows to combine experimental records into reusable sets. Such sets of records are referred to as baskets.
Baskets have names and user can virtually have as many baskets as required. Baskets are typically used as training or validation sets for the development of QSAR models.
Baskets as sets of molecules
Usually, baskets contain the experimental data records. However, baskets can contain molecules without any experimental data attached.
In this case, baskets serve as sets of molecules.
