Hi, I have a quick question about centering different PDB files. Currently I'm working with 4 different PDB files that need to be centered on the 0,0,0 coordinate. Unfortunately, I have not had much success so far since each PDB file opens up in different locations given their own coordinate systems. Is there a software (preferably free/opensource) that will allow me to center all the PDBs on the world origin and save them back out? Thank you for all your help, Gunnar Vikberg
