Detailed Description

Database of default hybridization torsional rules and SMARTS-defined OBRotorRule objects.

Use to automatically evaluate potentially rotatable bonds to generate lists of dihedral angles to consider. e.g., rotamer/conformer energy calculations

Member Function Documentation

void ParseLine

(

const char *

)

[virtual]

Specified by particular table classes (parses an individual data line).

Reimplemented from OBGlobalDataBase.

size_t GetSize

(

)

[inline, virtual]

Returns:

the number of rotor rules

Reimplemented from OBGlobalDataBase.

void SetFilename

(

std::string &

s

)

[inline]

Set the filename to be used for the database. Default = torlib.txt.

void GetRotorIncrements	(	OBMol &	mol,
		OBBond *	bond,
		int	refs[4],
		std::vector< double > &	vals,
		double &	delta
	)

Determine the torsional angles to evaluate based on the database

Parameters:

	mol	molecule to evaluate
	bond	rotatable bond to evaluate
	refs	set to be the atom indexes (in mol) of the dihedral angle
	vals	set to be the list of angles to evaluate (in radians)
	delta	potential dihedral angle steps (in degrees)

Referenced by OBRotorList::AssignTorVals().

void Quiet

(

)

[inline]

Turn off debugging output from GetRotorIncrements().

void Init

(

)

[inherited]

Read in the data file, falling back as needed.

void SetReadDirectory

(

char *

dir

)

[inline, inherited]

Set the directory before calling Init().

void SetEnvironmentVariable

(

char *

var

)

[inline, inherited]

Set the environment variable to use before calling Init().
