what is so difficult about it?? you can just write a little script using awk/perl/python/tcl/... to do one translation/scaling operation and then cut and paste the final (or initial) alat based coordinates from a previous run into this and piece the different translations together and make one input from it. this needs to be adjusted most of the time anyways. cheers, axel. > Best Regards, Piero > > Nobody knows any shortcut to avoid to write it by hand? > > ----- Original Message ----- > From: Stefano Baroni <baroni at sissa.it> > Date: Friday, April 24, 2009 4:31 pm > Subject: Re: [Pw_forum] how can I create a supercell in PWSCF? > To: PWSCF Forum <pw_forum at pwscf.org> > > > xcrysden? > > SB > > > > On Apr 24, 2009, at 3:55 PM, Pieremanuele Canepa wrote: > > > > > Dear all, > > > does exist a script or a small program in Quantum > > espresso that > > > allow me to create a suitable supercell (for instance > > 2x2x1) > > > starting from a primitive cell of PWSCF? > > > Best regards, Piero > > > > > > -- > > > Pieremanuele Canepa > > > Room 230 > > > School of Physical Sciences, Ingram Building, > > > University of Kent, Canterbury, Kent, > > > CT2 7NH > > > United Kingdom > > > ----------------------------------------------------------- > > > > > > _______________________________________________ > > > Pw_forum mailing list > > > Pw_forum at pwscf.org > > > http://www.democritos.it/mailman/listinfo/pw_forum > > > > --- > > Stefano Baroni - SISSA & DEMOCRITOS National > > Simulation Center - > > Trieste > > http://stefano.baroni.me [+39] 040 3787 406 (tel) -528 (fax) > > / > > stefanobaroni (skype) > > > > La morale est une logique de l'action comme la logique est une > > morale > > de la pens?e - Jean Piaget > > > > Please, if possible, don't send me MS Word or PowerPoint > > attachmentsWhy?
