R: Manipulate PDB File Names

basename.pdb {bio3d} | R Documentation

## Manipulate PDB File Names

### Description

Removes all of the path up to and including the last path separator (if any) and the final ‘.pdb’ extension.

### Usage

    basename.pdb(x, mk4 = FALSE, ext=".pdb")

### Arguments

`x` | character vector of PDB file names, containing path and extensions.
`mk4` | logical, if TRUE the output will be truncated to the first 4 characters of the basename. This is frequently convenient for matching RCSB PDB identifier conventions (see examples below).
`ext` | character, specifying the file extension, e.g. ‘.pdb’ or ‘.mol2’.

### Details

This is a simple utility function for the common task of PDB file name manipulation. It is used internally in several bio3d functions and van be thought of as basename for PDB files.

### Value

A character vector of the same length as the input ‘x’.

Paths not containing any separators are taken to be in the current directory.

If an element of input is ‘x’ is ‘NA’, so is the result.
