SAPTF (Sequence Analysis Plugin Tools Framework) is designed as a very simple way to provide sequence analysis tools on the web. It saves all the effort of creating the actual pages and CGI scripts - all that is needed is the tool itself (which can return HTML or just plain text) and a simple XML configuration file. SAPTF will even deal with very slow long-running programs (like BLAST or ClustalW) which might make the user wonder whether anything is happening, or may need some sort of wait-page to stop the web server from timing out - SAPTF deals with this through AJAX.

As an example, we are using SAPTF in PAPS, our antibody VH/VL packing angle prediction server.


You can see a demonstration which runs a simple tool to calculate amino acid frequencies and shows the 'slow' and 'very slow' AJAX modes for dealing with slow long-running programs.

This page was created using this simple XML configuration file.
