WebNov 17, 2024 · The flat-bottom restraint is available as “FB” in the [RESTRAINTS] section in the GENESIS control file. In GENESIS, FB is defined as: U (R) = K (R-R_0)^2 if R > … WebPosition restraints are typically implemented by adding a harmonic force that binds each particle to its initial position. The further it moves, the stronger the force pushing it back. This is generally done by adding a CustomExternalForce to the System. As an example, let’s copy the beginning of the simulatePdb.py script from the examples ...
