2012

• March 21.
  • New [Write PDB...] button in the G-LE window to write a PDB file at its new 3D position. WARNING: this only writes the (modified) ATOM/HETATM records in the new file (The other PDB record are not copied into the new file).
  • New [fix position] command in the [LifeExplorer] menu: this copies the world coordinates of the object into the local coordinates and resets the local-to-world transformation matrix. Use this prior to saving a Mesh/Surface if you want it to be exported at the same position as in the Graphite 3D window. Warning: after the command is started, there is no way to get back to the original local coordinates (except if these were already saved in some file).
• March 9.
  • The base-pair tuning tool is now better at finding the atom that you clicked on. Also, when clicking an atom, the base-pair number and the atom name is displayed (at the bottom of the window)
  • New name : Graphite - LifeExplorer
• March 5. Fixes opacity bug in the DNA rendering and the "Curve to tubular surface" command.
• February 29. Fixes a crash triggered by tubular surface creation.
• February 16. Meshing a PDB file takes into account the global translation/rotation of the corresponding PDB (Line object). The command for loading point sequences is cleaner and in the LifeExplorer menu. The other commands appear in the "MM Curve" menu.
• February 7. Added a tool for moving an object in space, globally.

2011

• November 2. Graphite's very basic user guide.
• October 19. New release for Mac OS X:
  • twisting and PDB export should work correctly with closed DNA.
  • Much (much) faster coloring of residues on molecular surfaces.
• October 18. We are working on making circular (closed loop) DNA work correctly with custom twisting and PDB export. In the picture below: Left, modeling a closed DNA strand with a cubic Bezier curve and some custom local twisting (see the lighter base pairs). Middle, the corresponding exported PDB model. Right, a colored molecular surface generated from the PDB. (Click to enlarge.)
  
  The feature seems ready and will be included in future releases.
• October 12. We give a talk about MicroMégas at the "Journée Visu 2011."

• October 4. We have a brand new mailing-list! Check this link to subscribe.
• September 29. The Mac application has been updated to fix the search for internal (GEL) files, which were not found.
• September 27. Graphite with its MicroMegas plugin is now available as a standalone application for Mac! (Download link in the Mac section below).
• September 2. Now features the DNA-twist tool, that lets you select a base pair and twist it. You can abuse it to produce flat DNA for example, or simply to locally adjust the position of the base pairs.
