HasXWaters: Has "X" Waters

In vanddraabe: Identification and Statistical Analysis of Conserved Waters Near Proteins

Description

Determines if PDB structure has water molecules.

Usage

HasXWaters(atoms.oi.resid, min.num.h2o = 20)

Arguments

atoms.oi.resid	vector of character strings containing the standardized three-letter amino acid residue names
min.num.h2o	numeric value indicating the minimum number of water molecules required to return a TRUE logical value

Details

Determine if the PDB structure has at least the user defined number of water oxygen atoms. The number of water oxygen atoms is returned along with a logical value indicating if the structure satisfies the user defined minimum.

Waters are identified using the three water three-letter residue names: HOH, WAT, and DOD.

Value

logical indicating if the PDB structure has the minimum user defined number of waters

numeric value indicating the number of water oxygen atoms within the PDB structure
