def demo.D090_Ala_scan.mutate_residue	(		pose,

	)

Replaces the residue at  <mutant_position>  in  <pose>  with  <mutant_aa>
    and repack any residues within  <pack_radius>  Angstroms of the mutating
    residue's center (nbr_atom) using  <pack_scorefxn>
note: <mutant_aa>  is the single letter name for the desired ResidueType

example:
    mutate_residue(pose, 30, A)

scanning()

def demo.D090_Ala_scan.scanning	(		pdb_filename,
			partners,
			mutant_aa = 'A',
			interface_cutoff = 8.0,
			output = False,
			trials = 1,
			trial_output = ''
	)

Methods.

Performs "scanning" at an interface within  <pdb_filename>  between
    <partners>  by mutating relevant residues to  <mutant_aa>  and repacking
    residues within  <pack_radius>  Angstroms, further repacking all
    residues within  <interface_cutoff>  of the interface residue, scoring
    the complex and subtracting the score of a pose with the partners
    separated by 500 Angstroms.
    <trials>  scans are performed (to average results) with summaries written
    to  <trial_output>_(trial#).txt.
    Structures are exported to a PyMOL instance.

scanning_analysis()

def demo.D090_Ala_scan.scanning_analysis

(

trial_output

)

Average the values of all files in this directory with  <trial_output>  in
    their title and return the mutations (rows) that are 1 or more standard
    deviations from the mean score change
