# simplest case, save output to file

# compat mode
pdb4amber -i my.pdb -o out.pdb

# pipe
cat my.pdb | pdb4amber -o out.pdb

# save to different formats (e.g: mol2)
pdb4amber my.pdb -o out.mol2

# use `reduce` program to add hydgron
pdb4amber my.pdb --reduce -o out.pdb

# process other formats (e.g: .cif)
pdb4amber my.cif --reduce -o out.pdb

# process from URL
