Hello, >I've always wondered if we could hack that a bit to store information >in the file format. That way you could display surfaces/cube data >around the molecule and use Ghemical for a viewer for other program >data. (Displaying MOs from other programs would be great too, but >that's a different subject.) BTW, i'm extremely interested in surface properties for descriptor calculation tasks and pharmacophore models !!!! Please let me know any further progresses in this direction, i promise i will add some nice surface descriptors and pharmacophore models to JOELib, if i'm able to activate this interface correctly (or a student will do this). Unfortunately during the semester it's really hard to find time for such things ... and some example code, like the simple_test (mmtest) class would help me very much, because i'm not that familiar with your API.
