• MR using CCP4i:BETA/BLIP
• MR using keyword input
• Finding a search model:TOXD
• Molecular replacement with MRage
• SAD using CCP4i
• Combined MR-SAD using CCP4i
• EP using Phenix
• SCEDS using CCP4i
• SCEDS for MR
• NMA Coordinate Perturbation using CCP4i

Coot script for Normal Mode Analysis - Perturbations (NMAXYZ)

To add a button to Coot to convert all loaded molecules to CA representation (C-alphas/backbone in the Display Manager) put the following script (called e.g. all-to-ca.py) in your .coot-preferences directory. Jiffy courtesy of Paul Emsley.

 def all_molecules_to_CA():
   for imol in model_molecule_list():
       graphics_to_ca_representation(imol)
 coot_toolbar_button("CA", "all_molecules_to_CA()", icon_name="6-c.svg")
 coot_toolbar_button("pre-CA", "set_default_representation_type(4)",icon_name="5-c.svg")

Data

The coordinate (pdb), sequence (fasta) and reflection (mtz) files required to run the MR tutorials are distributed with Phaser.
