forgi.threedee.utilities.virtual_residues module¶

forgi.threedee.utilities.virtual_residues.parse_vres(parts)[source]¶

Go back from a splitted serialized representation to a dictionary used for vres.

Parameters:	parts – A list of strings which hold floats. The length has to be a multiple of 3. Like a list gegerated by serialize_vres(vpos).split()
Returns:	A dictionary {nucleotide_number: coordinated}. See param vpos of the function serialize_vres

forgi.threedee.utilities.virtual_residues.serialize_vres(vpos)[source]¶

Output carthesian coordinates for each virtual residue, ordered by nucleotide number and seperated by space.

The returned coordinates are relative to the element’s coordinate system.

Parameters:	vpos – A dictionary {nucleotide_number: coordinates}. nucleotide_number is an integer with 0 referring to the first nucleotide of the element. coordinates is a 3-element 1D numpy array nucleotide_numbers should be consecutive integers.
Returns:	A string with space-seperated numbers. Groups of three numbers are x,y,z coordinates of one residue.
