We can let Jmol create the MO from the QM data in the browser - I think that is what we are doing now with the .mo file - but we greatly prefer to read the QM data from the database, not from a file.

I'm still trying to understand the mutual dependencies among load, isosurface, and mo.

When I use "jmolLoadInline()" with the contents of the .mo file, I can see the structure, and I can use the script "mo" (as implemented by the jmolMenu() JS command) to display the MOs.


By .MO file, not sure what you mean there, unless that's a WebMO file. The fact that  you can use the MO command indicates that you are creating the orbitals from the basis functions and coefficients.
 
When I use "jmolLoadInline()" with the contents of the .jvxl file, I can see the structure, but I cannot find a script that will display the isosurface.  Is there a script that will display the isosurface after I load it into Jmol with "jmolLoadInline()"?



This older JVXL file format was modeled on the CUBE format and thus did save up to the first 100 atoms; the newer XML version doesn't. But all you are doing there is reading the atoms. The load command doesn't read any surfaces ever. If the file has QM basis and coefficients, then those are read at load time (and the popup menu will be populated with items showing all the orbitals and their energies).

The JVXL file is really a surface file and is read using the ISOSURFACE command. Until last week you couldn't load those inline. (You could load PMESH data -- simple triangles -- inline, but you couldn't use the isosurface INLINE keyword with anything else. I think I changed that early last week. So if that's really what you want to do, you need to use Jmol 11.9.21.

So you can load MO data two ways -- with the LOAD/MO command combination or with the ISOSURFACE command. In Jmol "MO" is a subset of "ISOSURFACE" so the same code is run, but the options are a bit different. When you use

MO homo

you get a basic, standard orbital, with a nice listing of orbital properties in the upper left corner. Options are pretty much limited to cutoff and color. With

ISOSURFACE MO homo

you don't get that listing, but you have a bit more flexibility -- you can, for example, choose to ignore atoms and only see contributions from a subset, and you can do contouring, planar slices, "topo" maps, and such. I need to get this into the documentation....

I think it just got mangled as being part of the email.

isosurface is used to create MOs from files that are not QM files. -- surfaces.
mo is used to generate the MO data directly from the basis functions. Most people these days, I think, just let Jmol read the QM file and create the MO in the browser -- no need for a server end. Are you certain you can't do that?

Hi Bob,

The information is read from an Oracle database and written into a JSP page.  We have the ability to write information to files, but we want very much to avoid having to do it.   We also want to avoid having to deal with multiple files to display a single molecule and its associated MOs.  From my point of view, Jmol's preference for loading information from files is a real drawback.

We worked around the problem by using a .mo file instead of a .jvxl file.  We were able to load the .mo file inline and display its MOs without any problem.  A friend gave us the proper Jmol JS commands to use to display the MOs.  jmolMenu([['mo delete;','none'],['mo 3',"3"],['mo 4',"4"] ...]); . No "isosurface" commands.

I don't think that we could have mangled the .jvxl information because the .mo information, which was loaded and transmitted in exactly the same way, was not mangled.  But I could be wrong.

So is it correct that we use "isosurface" to load MOs into Jmol, and we use "mo" to induce Jmol to display them?

Well, two things. First, you must have mangled the data some way - or at least clipping from this page doesn't work. Because the attached file did run. Second, you can only load an isosurface "inline" like that in the very latest version of Jmol. (I'm not sure it's even in the one I have up at http://chemapps.stolaf.edu) What you would need to do is (all Jmol script here)

isosurface INLINE @{javascript("getMol()")}

that tells Jmol to read the output of the JavaScript getMol() function as the data for the isosurface instead of reading the data from a file.

Any reason you don't want to have that data in a file? -- or is this coming back from a server and you are trying to keep it all together? Sure would be simpler:

isosurface "somefile.jvxl"

Hi,

I have a JVXL file containing MO data that I am trying to display.  I can see the molecule, but I can't see the MO.  I have tried various scripts to turn on the MO, to no avail.  Below I have copied the relevant part of my Web page.  I am using 'mo HOMO;' as the script, but I have tried several other commands, including none, to no avail.  How do I display the MO?  Does the fact that I load inline prevent the MO from being displayed?
