Molby - A Molecular Modeling Software

Fork

Local execution of GAMESS is implemented.
For X-ray data (with standard deviations), calculation of bonds and angles with standard deviation is implemented.
GAMESS log containing F and G type orbitals can now be imported (cube calculation is not yet implemented).
In the 'GAMESS export' dialog, new basis sets can be loaded from external files.
Particle mesh Ewald calculation is implemented (experimentally).
"Pi-anchor" atoms (i.e. dummy atoms for cyclopentadienyl-metal bonds etc.) are implemented (experimentally).
The Ruby console now has history capability.


Bug Fix:
CIF files from old TeXsan software cannot be loaded. Fixed.
Symmetry expansion in CIF import is improved (may not be complete yet).
Deleting bonds was causing bus error. Fixed.
Two subsequent dragging of different atoms was causing undo failure. Fixed.
Merging/unmerging molecules are revised, so that undo works more consistently.
And many others.

Document is updated for local execution of GAMESS and invocation of Antechamber.
Antechamber command is made more visible (e.g. when MM/MD parameters are not complete, user is asked whether to invoke antechamber).
Local execution of GAMESS is implemented.
Kernel#show_console_window, Kernel#hide_console_window, Kernel#filecopy are implemented.
Kernel#call_subprocess can now accept a callback procedure.
Importing PM3/GAMESS log is improved. (The atomic information was not recognized correctly)
On creating PM3 input for GAMESS, NGAUSS=3 is also specified
Calculation of bonds and angles with standard deviations (for X-ray data) is implemented.
CIF files from old TeXsan software cannot be loaded. Fixed.
Symmetry expansion was incomplete in CIF import. Improved, but may not be complete yet.
GAMESS log containing F and G type orbitals can now be imported. (MO calculation is not yet implemented.)
export_gamess is modified so that arbitrary keyword/value pairs can be given.
Bond creation is updated so that duplicate bond/angle/dihedrals are not generated.
Molecule#neutralize was not working. Fixed.
Copyright statement was updated to include FFTW.
Deleting bonds was causing bus error. Fixed.
MSW: when the console frame gets focus, all text was selected instead of the previous insertion point getting restored. Fixed.
Handling of GAMESS basis set is modified. The 'external' basis set files are now collected in Scripts/basis_sets. Also implemented is a button in the 'GAMESS export' dialog to load other basis set files.
Calculation of reciprocal cell parameter was incorrect. Fixed.
Some wrong behavior of PME calculation is fixed.
An error in PME energy calculation is corrected. MDArean#ewald_order is implemented.
Error message in Molecule#atoms[] was not working. Fixed.
Particle Mesh Ewald calculation is implemented (experimental). MDArena#use_ewald, ewald_beta, ewald_grid, ewald_freq are implemented.
Molecule#expand_by_symmetry was not working correctly when no symmetry operations are defined (and expansion with only translation is specified). Fixed.
Change in Antechamber/Resp dialog: molecular charge can be always assigned, and 'optimize' checkbox is no longer visible in the Resp dialog
In calling a subprocess, a wait of 10 msec is inserted between termination check (may be or not useful for more stable handling of subprocesses...?
Suppress output of pi-anchors when generating GAMESS or Gaussian input files.
Utility methods Enumerable#sum and Enumerable#average are implemented.
When new bonds are created, angles of type X-##-## (## is pi-anchor) should not be automatically added.
Parameter lookup was not working correctly when neither local or global search is specified and 'missing' is turned on. Fixed.
'==' operator is defined for Parameter, ParameterRef, AtomRef, ParEnumerable, MolEnumerable, and Molecule classes.
Create Pi Anchor menu command is implemented.
Parameter#lookup (and related methods) can now look up parameters from the atom indices, even when the parameter is described in atom types.
History functionality is available in the Ruby console. Handling of fonts in Windows version is improved.
Parameter methods angle, angles, bond, bonds, etc. can now be used as singleton methods (i.e. Parameter.element(1) is now allowed)
Flashing of the table while pressing the shift key (and other modifier keys) is reduced.
Symmetry expanded atoms now can be selected by mouse drag.
Expanding by symmetry (and loading cif file) was not working correctly. Hopefully fixed.
Attribute table was not updated correctly after revert. Fixed.
Revert command is implemented.
Atom renumbering was not working for pi anchor table. Fixed.
Two subsequent dragging of different atoms were causing undo failure. Fixed.
Remove previous pi-anchor codes.
"Pi anchor" atoms are implemented.
The load/save codes are rewritten, so that the error/warning messages are shown in the console.
Merging/unmerging molecules are extensively revised. Hopefully undo works more consistently than before.
The third argument to Molecule#get_coord_from_frame() is now obsolete, but causes warning instead of ArgumentError
Molecule#get_coord_from_frame now always tries to copy the cell information.
Kernel#exit is now untouched in the command line version. The command line version now displays version message on startup.
Molecule#cell_flexibility, set_cell_flexibility are obsolete, and the unit cell is always flexible (i.e. different frames can have different cells). Molecule#cell_periodicity and set_cell_periodicity are implemented.
