GAMGI 0.13.14

GAMGI 0.13.14 is an all-in-one program which can build, view, and analyze atomic structures, as powerful and simple to use as possible.

GAMGI aims to be useful for:

• The scientific community working in atomistic modeling, who needs a graphic interface to build and analyse atomic structures
• The scientific community at large, who needs a graphic interface to study atomic structures and to prepare images for presentations
• Teaching the atomic structure of matter in schools and universities, even inviting students to run GAMGI at home
• Science promotion, in exhibitions and science museums.

Enhancements:

• Fixed a couple of bugs in chem and gtk code, including a nasty brown paper bag that crashed the new polytope code in many systems.
• Everything that can be measured with Atom->Measure can now be modified with the new Atom->Modify dialog.
• The oldest dialog in Gamgi, Group->Modify, has been replaced by an entirely different dialog, to modify Groups, including polytopes.
• Added bond cleaning when creating Polytopes and improved this cleaning for Planes and Directions.
• Improved layout for View page in Atom->Create and Atom->Modify. Variance is now a combo box entry, with 0.0 and 1.0 suggestions.
• Improved layout for View page in Bond->Modify and Atom->Modify.
• Fixed position for Autonomy combo box in Plane->Modify and Direction->Modify dialogs.
• Completed interface behaviour in Group->Modify dialog.
• Improved Scale behaviour in Group->Modify, Plane->Modify, Direction->Modify dialogs.
• Replaced Property by Quantity in Plane->Measure and Direction->Measure dialogs.
• Designed and implemented the new Group->Modify dialog.
• Modifying atom-2atom distances is now working fine. All the quantities that can be measured with Atom->Measure can now be modified with the new dialog Atom->Modify.
• Modifying atom-direction distances is now working fine.
• Modifying atom-3atom distances is now working fine.
• Modifying atom-plane distances is now working fine for all cases.
• Fixed a old bug when modifying a torsion angle: the terminal branches of the second atom should change as well, not just the first atom and its terminal branches.
• The only task dialog in GAMGI still from the first generation, Group->Modify, has been removed. It will be replaced soon by a dialog handling Polytopes, among other things.
• All the functionality previously available in Group->Modify is now available in Atom->Modify, in the mode Geometry.
• Completed all the GTK code for the new Atom->Modify dialog.
• The new Atom->Modify dialog will be used to set all the quantities that are measured in Atom->Measure, replacing the old Group->Modify dialog that will be used to modify Group objects such as polytopes.
• The new Atom->Modify dialog is almost finished: removed a sync bug resulting in a GTK warning.
• Found and removed a bug in gamgi_chem_geometry.c: sequence array off limits by 1, for bond angles.
• Removed all warnings at -O3 compilation level, on Fedora 9.
• Found and removed a crashing bug in gamgi_chem_polytope.c: in static_vertex_create, first total should not be there.
• Found and removed a bug in gamgi_gtk_atom_modify.c: when style changes, update draw, not atom->draw.
• Designed the new Group->Modify dialog: based on Atom->Measure and Group->Create, the first page has radio buttons to jump between the two sets of pages (Atoms and Polytope). Opens initially in one of the two sets (Atoms), in the second page, to preserve a rule always followed in GAMGI GUIs: users are required to fill only the starting visible notebook page, all the others are optional or have suitable defaults.

Requirements:

• Hardware requirements:
• • To run properly, GAMGI requires a graphics environment with with at least 16 bits per pixel, otherwise object selection with the mouse does not work, and using GAMGI becomes much more difficult.
  • GAMGI requires a 3-button mouse to work properly, as the mouse buttons are one of the ways to rotate, move and scale objects. With a 2-button mouse, users can configure the button order for example to discard scale and use move and rotate modes only.
• Software requirements:
• • GAMGI can be installed on any computer running Linux/Unix with the standard X Window System. GAMGI requires the following libraries: Glib/Gtk, Mesa, Gtkglarea, Expat and Freetype.
  • GAMGI should run with any version of Glib/Gtk 1, but does not even compile with Glib/Gtk 2. GAMGI should run with any version of Mesa or OpenGL, though a recent release is recommended, due to some bugs. GAMGI should run with any version of Gtkglarea 1. GAMGI should run with any version of Expat. GAMGI should run with any version of Freetype 2, but does not even compile with Freetype 1.
