This service gives access to the Pfrag homology modelling program. Pfrag uses the segment matching method to insert fragments of structure, taken from a database of high quality structures. The mathing is based on local sequence similarity, van der Waals contacts and a RMSD superposition.
The program takes two inputs, an alignment and one template structure. The format of the alignment is the following:
>Name of target sequence
One letter residue sequence
>Name of template sequence
One letter template sequence
Note that the template sequence needs to match exactly the given template structure, and gap positions are denoted by "-".

Test #1: Pfrag test
This test sends a small Pfrag-alignment and a template stucture, and expects in return a model based on the input files
