In bio3d: Biological Structure Analysis

Concatenate Multiple PDB Objects

Description

Produce a new concatenated PDB object from two or more smaller PDB objects.

Usage

cat.pdb(..., renumber=FALSE, rechain=TRUE)

Arguments

...	two or more PDB structure objects obtained from read.pdb.
renumber	logical, if ‘TRUE’ residues will be renumbered.
rechain	logical, if ‘TRUE’ molecules will be assigned new chain identifiers.

Details

This is a basic utility function for creating a concatenated PDB object based on multipe smaller PDB objects.

Value

Returns an object of class "pdb". See read.pdb for further details.

pdb2 <- read.pdb("1hel")

## Concat
new.pdb <- cat.pdb(pdb1, pdb2, pdb1, rechain=TRUE, renumber=TRUE)

## Write to file
write.pdb(new.pdb, file="concat.pdb")
