Concatenate Multiple PDB Objects

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

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.

Examples

if (FALSE) {
## Read a PDB file from the RCSB online database
pdb1 <- read.pdb("1etl")
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")
