[modeller_usage] Restraints in table 6.1

[abdullah ahmed <>]

Dear Modeller users,

I have a few very long (and perhaps naive) questions regarding "Table 6.1: List of physical Restraints types"

1. If the Hydrogen bonding restraint is applied, does it automatically incorporate all possible Hydrogen bonds in the file, or do the specific hydrogen bonding atoms have to be specified? (Also could you maybe provide a short piece of code showing how this restraint can be applied?)
2. Are the Phi, Psi, omega, and Chi restraints used to lock the angles of the backbone and the the side chain into specific values or are they used for something else all together?
3. What do the accessibility, absposition, dihedral_diff and SAX restraints do?

Thank you in advance for your replies,
Abdullah Ahmed
