     1. About the method

         J-PBPS is a program to predict from the sequence local structures encoded in a structural alphabet called Protein Blocks. The approximation of 3D structure by the PBs is correct and allows a description closer to the reality than a simple 3-states alphabet (secondary structures). Then, the prediction of the local 3D structures from the sequence is done using a Bayesian approach with a rate of 34.2 %. This rate increases to 40.7 % by subdividing by an unsupervised method the most frequent PB on their sequence specificity. The local information is more informative than expected, 75.8 % of the true PBs are finding again among the fourth most probable PBs for the Bayesian approach. Please see de Brevern, Etchebest and Hazout [1] for detailed description of the algorithm.

         All rights reserved, whether the whole or part of the program is concerned. Permission to use this software and its documentation is granted for academic use, provided that:

         i. this copyright notice appears in all copies of the software and/or related documentation;

         ii. the reference given below (de Brevern et al., 2000) must be cited in any publication of scientific results based in part or completely on the use of the program;

         iii. bugs will be reported to the authors.

The use of the software in commercial activities is not allowed without a prior written commercial license agreement (please write to debrevern@urbb.jussieu.fr and hazout@urbb.jussieu.fr).

     3. Availability

         J-PBPS is written in Java 2 with jdk 1.3.0 and so could be use with several UNIX platforms, Windows 95, 98 and 2000, MacOS using IE 4.x or Netscape 5.x or newer. The prediction site will always be at the EBGM site (Equipe de Bioinformatique Genomique et Moleculaire) which is now http://condor.urbb.jussieu.fr. The java bytecode (.class) are avalaible to academic users for local use from request to debrevern@urbb.jussieu.fr. The source code (.java) is only avalaible to commercial users after license agreement.

         Due to some limitation of IE and Netscape, the use of the "real" appletviewer will limit the errors.

     4. Bug reports and user feedback

         Please send your suggestions, questions and bug reports to debrevern@urbb.jussieu.fr. Send your contact address to get information on updates and new features.
