Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: New IO Format Group: None Status: Open Priority: 5 Private: No Submitted By: Laurence Marks (ldm001) Assigned to: Nobody/Anonymous (nobody) Summary: Wien2k + vibrations Initial Comment: Can you please provide a reader for Wien2k DFT files www.wien2k.at (I can provide format info etc). Also, can you provide information on how to input vibrational modes; I am writing an interface for these so can produce a file in the "appropriate" format, if someone tells me what! ---------------------------------------------------------------------- >Comment By: Laurence Marks (ldm001) Date: 2009-05-14 16:26 Message: Web source: http://www.wien2k.at/reg_user/textbooks/usersguide.pdf I've attached Ti2O3.struct converted to a standard cif Hunting a bit more, I think Angstroms have vanished from all the cases, so please assume that everything is in BOHR (even if that key is not there) and just ignore the units. I'll put some additional cases in shortly (alas, it deletes the message if not sent). ---------------------------------------------------------------------- Comment By: Bob Hanson (hansonr) Date: 2009-05-14 16:14 Message: Oh, just saw that latest comment --- ANG like that, in caps? unit=ANG or unit=ang right now I see unit=bohr not unit=BOHR OK, I'll try fixing the coordinate values for R. Some examples of the F, B, I, C$$ cells would be helpful. So you mean the symmetry operations are not complete? Really? ---------------------------------------------------------------------- Comment By: Bob Hanson (hansonr) Date: 2009-05-14 16:11 Message: I could use a bit more information -- web source for that PDF guide? -- check of the Ti2O3 structure. ---------------------------------------------------------------------- Comment By: Bob Hanson (hansonr) Date: 2009-05-14 15:09 Message: OK, check out http://chemapps.stolaf.edu/jmol/docs/examples-11/new.htm http://chemapps.stolaf.edu/jmol/docs/examples-11/Jmol-11.jar contains the files. I think there is a problem with Ti2O3.struct -- it doesn't say BOHR, but it looks like Bohr, and I'm not convinced the rhombahedral cell is loading properly. I might need some help with that. But please check all of them to see if they are loading properly.

The files you have provided should provide plenty of examples. Jmol should be able to read the unit cell and symmetries and derive all additional atoms from just the first atom in the set. This will be a good test, of course, since the additional atom positions are also given. I'll give it a try. ---------------------------------------------------------------------- Comment By: Laurence Marks (ldm001) Date: 2009-05-14 10:23 Message: I've attached some examples, as well as the relevant part of the documentation. Fairly self evident and the Space Group numbers/names are normally correct although it is more robust to use the symmetry. Are all the atoms needed (as against the symmetry reduced set)? It is simpler to use the reduced set although I can also do the full set. Also, does Jmol understand about "F", "B", "I" cells etc to know that these operations are implied or will it need more information? (For assorted reasons A, B, or C centered cells are coded differently in Wien2k.) ---------------------------------------------------------------------- Comment By: Jonathan Gutow (gutow) Date: 2009-05-14 10:15 Message: As there is money being collected for distribution of Wien2k, I suggest that the Wien2k project should put some programmer time into developing the file reader if they want Jmol to read their files. Jonathan ---------------------------------------------------------------------- Comment By: Bob Hanson (hansonr) Date: 2009-05-14 09:47 Message: please attach a few file examples. Vibrational modes are read along with file data, so if your file format included vibrational mode information then that could be automatically incorporated. If your vibrational information must be separate, then I recommend the extended XYZ format. This is simply: # of atoms comment line [atom line] [atom line] [atom line] [atom line] ... where the atom line is simply: element x y z vibx viby vibz For example: 3 CoolMolecules Vibration Generator O 0 0 0 0 0.005799922848714869 0 H 0.7698177590299584 -0.5480927092035551 0 0.06516975737819754 -0.04639938278971895 0 H -0.7698177590299585 -0.548092709203555 0 -0.06516975737819754 -0.04639938278971894 0 For multiple modes, you just string as many of those together as you want: 3 CoolMolecules Vibration Generator mode 1 O 0 0 0 0 0.005799922848714869 0 H 0.7698177590299584 -0.5480927092035551 0 0.06516975737819754 -0.04639938278971895 0 H -0.7698177590299585 -0.548092709203555 0 -0.06516975737819754 -0.04639938278971894 0 3 CoolMolecules Vibration Generator mode 2 O 0 0 0 0 0.005799922848714869 0 H 0.7698177590299584 -0.5480927092035551 0 0.06516975737819754 -0.04639938278971895 0 H -0.7698177590299585 -0.548092709203555 0 -0.06516975737819754 -0.04639938278971894 0 3 CoolMolecules Vibration Generator mode 3 O 0 0 0 0 0.005799922848714869 0 H 0.7698177590299584 -0.5480927092035551 0 0.06516975737819754 -0.04639938278971895 0 H -0.7698177590299585 -0.548092709203555 0 -0.06516975737819754 -0.04639938278971894 0 And if you want to include charge, you can do that between z and vibx: element x y z charge vibx viby vibz ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=379136&aid=2791729&group_id=23629 ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Jmol-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/jmol-developers
