Hi Teri, MAIN can do it: "http://www-bmb.ijs.si/".
this script will help you: read file xx.pdb coor pdb set coor sele all end deortho write over file xx_fract.pdb coor pdb standard for the opposite conversion replace the "deortho" with "ortho". When the PDB file doc not contain the CRYST1 read a cell constants file before the PDB file. example of cell.dat file: 10.9 10 10 90 90 90.0 best regards, dusan On Jan 8, 2013, at 1:00 AM, CCP4BB automatic digest system <lists...@jiscmail.ac.uk> wrote: > Date: Mon, 7 Jan 2013 11:18:19 +0530 > From: Teri Arman <teriar...@gmail.com> > Subject: Re: Who invented PDB format? > > Fractional Coordiantes to Orthogonal Coordinates and Vice Versa > > Hi, I need help, how can I make coordiates of 100 of PDBs of different > space groups to fractional coordiantes and vice versa.
