Summary: mo's of a single atom

Initial Comment:
Hi,

My real plan at one point in time is to have Jmol show some fake hybrid 
orbitals for single atoms. (This is why I wrote earlier about the cube file and 
jvxl file problems/bugs I found).

Now I decided that I should be able to do this by modifying coefficients in a 
Spartan.spartan file and pretend that Spartan calculated the hybrids (this is 
how I did it earlier: modify coefficients, calculate surfaces and do screen 
captures). Then I would like to use the mo xx command to have Jmol show the 
hybrid orbitals.

To my surprise, I don't see any orbital when I do that for a single atom 
structure. If I calculate H2O, it works, but not a single atom.
Jmol knows that there are 9 orbitals in the file (since if I ask for mo 12, it 
tells me an index from 1 to 9 is required). I tried it with C and that worked 
(for mo's 1-4 of course), but not Fe.

Any idea why?

Just in case, I'll attach the Fe.spartan file.

Jmol cannot display MOs for calculations using a 5D basis set. (Standard
is 6D.) However, the Spartan smol reader was not indicating that the set
was 5D, so an exception was being thrown when it came time to do the
calculation. (There were too few coefficients.) If you look on your Java
console, you will see "Error in MO Calculation" displayed. 

I have made changes to 11.1.47 to handle this better; the Java Console
will now read in this case:

QuantumCalculation.checkCalculationType: can't read 5D basis sets yet:
PM3D     1 5D shells -- exit

At some future date, Jmol might be able to read a 5D basis, but for now,
if it is at all possible, try a different basis for the calculation. 

Bob
