EcoTox and PAS program
PAS is the program to estimate eco-toxicity from structure by structure-activity relationship and read across.

PAS provides a prototype of QSAR (Quantitative Structure Activity Relationship). PAS has the basic function of definition of partial structure (fragment) , searching logic and drawing of chemical structure.
PAS (version 1) was employed in KATE(KAshinhou Tool for Ecotoxicity; National Institute for Environmental Studies, Japan) as a program to estimate eco-toxicity.
The definition and search method for fragments is named as 'FITS'; Fragment Identification by Tree Structure'. FITS has developed and changed widely for an easy use at version 2.
It is possible to use the program as it is with or without fleshing out the database.The latest version is 2.00.04 (Deviced on 2017.11.01).
The reason why I provide the prototype is to facilitate the user to maintain own data, enables the changes of the program, and reconstruct own QSAR system.
