SPIN manual 1.1 : user’s guide version 1, for use with FOCUS_SWASH 4.2

This manual addresses the main functionalities of the Substance Plug IN tool, SPIN version 1.1, which is released together with FOCUS_SWASH 4.2 and FOCUS_TOXSWA 4.4.2. SPIN is basically a database that stores all substance properties relevant to the listed pesticide fate software. New substances can be added to the database by copying an existing substance or by creating a new substance. The database can also be copied and exchanged between (advanced) users, whereas substances can also be exported and imported. SPIN can be run in two different modes, either standalone, in which case all properties are accessible and can all be filled in, or when started from a host application, in which case only the host-required properties are accessible. SPIN has been developed such that all new releases of SPIN can communicate with earlier released host-applications
