    %h3 DEPRECATION NOTICE
    During the last months we have added a lot of capabilities and algorithms to our framework and tested them with extensive model building and validation. We finally came to the conclusion that the creation of good models still requires a lot of human intervention and that we cannot recommend a simple 1-click interface as in the current ToxCreate version.

    %br
      Until we have implemented an expert GUI interface you have the following options to construct models (

      We will keep the ToxCreate interface available for documentation purposes, but
      %em strongly discourage
      its use, because the resulting models may perform less than optimal.

    This service creates and validates new

    structure-activity models from your experimental data. The models can be used to predict toxicity of new chemicals (e.g. for 
    %a{:href => "http://ec.europa.eu/environment/chemicals/reach/reach_intro.htm", :rel => "external"} REACH
    purposes) and to reduce the need for animal testing.  The following methods are currently available:
  %ul
    %li
      = toggle_link("#lazar_description","lazar")
      %em= toggle_link("#classification","classification")
      models and
    %li
      = toggle_link("#lazar_description","lazar")
      %em= toggle_link("#regression","regression")
      models (experimental)

    Further modelling algorithms may be added in future versions.
