The ModFOLD Model Quality Assessment Server (Version 4.0)

NOTE: This version is no longer maintained. You are advised to use the latest version of ModFOLD, which is available here: ModFOLD home page

This form allows you to predict the quality of 3D models for a given protein target. Further information and references can be found on the ModFOLD home page. Before you submit a prediction please refer to the help page. Click 'Help' in each section for detailed instructions.

Required - Input sequence of protein target (single letter code) Help

Required - Upload model/models (either a single PDB file or a tarred and gzipped directory of PDB files) Help

Optional - E-mail address (you will be sent a link to graphical and machine readable results when the job is completed)Help

Optional - Short name for protein target Help
