Fixed Defects in TmoleX

  • For T and Th symmetry TmoleX displayed the number of electrons incorrectly in the Molecular Attributes panel. The error was in the visualization only, TURBOMOLE calculations have not been affected
  • The COSMOview molecule viewer showed inaccessible grey areas if the display of the molecule was enlarged (scaling of display > 100%). This problem is resolved
  • For Lithium TmoleX failed to read in def2-QZVP and dhf-QZVP basis sets
  • The creation of 3D electron density distributions (.plt, .plv) which can be visualized using BIOVIA TURBOMOLE was not working if used from an environment variable, which is fixed now. A workaround was available (direct call of the 3D electron density distribution program)
