Getting interface residues?

[Anonymous]

Hi everyone, I was looking through the source code of D090_Ala_scan.py, which contains code such as:

p = Pose()
pose_from_pdb(p, “aacap1_0290.pdb”)
starting_p = Pose()

#parameters
dock_jump = 1
interface_dist = 8.0 #angstroms
DockingProtocol().setup_foldtree(p)

scorefxn = create_score_function(‘standard’)
scorefxn(p) #needed for proper Interface calculation

interface = Interface(dock_jump)
interface.distance(8.0)

interface.calculate(p)

However, when I try to run the script, it says that Interface is not defined. Does anyone know how to access the Interface class in PyRosetta?

Thanks,

Julius

Which version of PyRosetta are you using? With the latest version of PyRosetta, the following works fine:

from rosetta import *
from rosetta.protocols.scoring import Interface

rosetta.init()

p = Pose()
pose_from_pdb(p, “input.pdb”)

scorefxn = get_fa_scorefxn()
scorefxn(p)

interface = Interface(1)
interface.distance(8.0)
interface.calculate(p)

Thanks rmoretti, this works great. I hadn’t known about the proper procedure to include the Interface class:

from rosetta.protocols.scoring import Interface
