Is there a command that sets a variable length?
I have a input of a variable length field but my output for that field needs to be set to 32 char.
Is there such a command?

pdb2pqr
PDB2PQR(1) PDB2PQR Manual PDB2PQR(1)
NAME
pdb2pqr - Generate PQR files for use in electrostatics calculations
SYNOPSIS
pdb2pqr [--nodebump] [--noopt] [--chain] [--assign-only] [--clean] [--ffout=name] [--with-ph=ph] [--apbs-input] [--ligand=path]
[[--verbose] | [-v]] --ff=forcefield path output-path
pdb2pqr {--help | -h}
DESCRIPTION
pdb2pqr automates many of the common tasks of preparing structures for continuum electrostatics calculations, providing a utility for
converting protein files in PDB format (path) to PQR format (output-path). These tasks include:
o Adding a limited number of missing heavy atoms to biomolecular structures
o Determining side-chain pKas
o Placing missing hydrogens
o Optimizing the protein for favorable hydrogen bonding
o Assigning charge and radius parameters from a variety of force fields
OPTIONS
pdb2pqr accepts the following options:
--ff=forcefield
The forcefield to use. Current values are amber, charm, parse and tyl06.
--help, -h
Print a help message and exit.
--nodebump
Do not perform debumping operation.
--noopt
Do not perform hydrogen optimization.
--chain
Keep the chain ID in the output PQR file.
--assign-only
Only assigns charges to add atoms, debump, or optimize.
--clean
Do no optimization, atom addition, or parameter assignment, just return the original PDB file in alligned format.
--ffout=name
Instead of using the standard caninical naming scheme for residue and atom names, use the names from the given forcefield.
--with-ph=ph
Use propka to calculate pKas and apply them to the molecule given the pH value. Actual PropKa results will be output to
output-path.propka.
--apbs-input
Create an APBS input file based on the generated PQR file. Also create a Python pickle for using these parameters in other programs.
--ligand=path
Calculate the parameters for the ligand in MOL2 format at the given path. Pdb2pka must be compiled.
--verbose, -v
Print additional information to screen.
EXTENSIONS
Extensions add functionality to PDB2PQR and are called by passing a parameter to pdb2pqr. They put their results into files located in
output-path.
The following extensions can be used by pdb2pqr:
--phi
Print the per-residue backbone phi angle to output-path.phi.
--psi
Print the per-residue backbone psi angle to output-path.phi.
--hbond
Print a list of hygrogen bonds to output-path.hbond.
--chi
Print the per-residue backbone chi angle to output-path.chi.
--contact
Print a list of contacts to output-path.con.
--hbondwhatif
Print a list of hydrogen bonds to output-path.hbo.
--salt
Print a list of salt bridges to output-path.salt.
--rama
Print the per-residue phi and psi angles to outpath-path.rama.
