Summary: MOs not showing for molden file

Initial Comment:
Hi,

I just, after a long time, updated the Jmol source with the repository and for 
one reason or another a molden file that works properly (after forcing it to 
consider it as a molden file since the header has ' [Molden Format]' with Jmol 
Version: 12.0.49  2011-07-30 15:57, does not show the molecular orbitals. I 
traced the interpretation of the file and it seems to me that it still indeed 
reads the orbitals and all, but doesn't display them. A test with the 
Jmol-datafiles molden sample water_novib.molden show that for that one I am 
able to show orbitals, so I am completely confused here.

I was hoping to change
if (leader.startsWith(recordTag)) (line 452 in Resolver.java) to
if (leader.trim().startsWith(recordTag))
so that leading spaces in the header would get ignored (and hoping that that 
would not break any other readers).

I'll try to attach the gzipped archive of the file to this report.
Thanks,
René

Yes, that's the same then as Gaussian, so we are good there. So far we only
support S-F.

Hi Bob,

The sample file I attached was for a multi-configuration calculation so
occupancy doesn't make much sense. Columbus just put 2's for every one of
them.
I just checked in a molden formatted file with the s, p and d orbitals for
an atom so one can see the order in which Jmol visualizes them.
The order according to the molden website
(http://www.cmbi.ru.nl/molden/molden_format.html) is 

The following order of D, F en G functions is expected:

   5D: D 0, D+1, D-1, D+2, D-2
   6D: xx, yy, zz, xy, xz, yz

   7F: F 0, F+1, F-1, F+2, F-2, F+3, F-3
  10F: xxx, yyy, zzz, xyy, xxy, xxz, xzz, yzz, yyz, xyz

   9G: G 0, G+1, G-1, G+2, G-2, G+3, G-3, G+4, G-4
  15G: xxxx yyyy zzzz xxxy xxxz yyyx yyyz zzzx zzzy,
       xxyy xxzz yyzz xxyz yyxz zzxy

which, I think (not sure) is indeed what Jmol does. It really is up to the
computational package to indeed use that ordering as well :-).

Thanks,
René

Rene, can you check on the order of coefficients for 5D and 7F for Molden?
Or at least confirm that various orbitals using those appear correctly.

I've modified the Resolver and also enabled reading of the [5D] [7F]
records in MoldenReader. Although I think there may be a bug in Molden --
it's reporting all occupancies = 1. Why would that be?

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
