Automated Web-Based Homology Modeling: There are some web based techniques to generate models of protein three dimensional structures which uses comparative modeling techniques.
• SWISS-Model: This can be accessed via ExPasy web server
• WHAT IF: This is available for EMBL servers. It has three components. One is to generate models, the other is to check the quality of modeling and the final one is to evaluate the models of proteins for which the structure is already known, thereby providing for assessment of the quality of the modeling program.
