CCL: new Chimera release (v1.8)

 Sent to CCL by: "Elaine  Meng" [meng .. cgl.ucsf.edu]
 Hello everybody,
 A new production release of UCSF Chimera (version 1.8) is available:
 http://www.cgl.ucsf.edu/chimera/download.html
 Download is free for noncommercial use.
 Platforms: Windows, Mac, Linux, including 64-bit versions (recommended
 for working with large datasets on machines with at least 4GB memory).
 New features include a REST interface, session thumbnail images,
 electric field line display, interactive arrow repositioning,
 improvements to Animation, Mac multi-touch trackpad support, and
 suport for new formats: AutoPack results, Rich Molecular Format,
 Gromacs 4.6 trajectories, Amira mesh (scalar).
 More details are given below; see release notes for the full list:
 http://www.cgl.ucsf.edu/chimera/docs/relnotes/1.8.html
 General:
 * new RESTServer tool (under Utilities) provides REST interface
 * text notes and thumbnail image can be saved along with a session,
  viewed in Restore Session file browser before opening a session
 * data items can be removed from the Rapid Access list
 * quit-Chimera confirmation default conditional instead of always
 * 2D Labels arrows can be repositioned interactively
 * Mac multi-touch trackpad support
 Structure Analysis and Modeling:
 * "connected fragment" inserted into selection cascade between
  residue and chain
 * H-bond and clash/contact detection can ignore intramolecular
  interactions
 * molecular surface parameters can be given in "surface" command
 * "split" command can split a model based on ligands, bonded sets
  of atoms, etc. (formerly just chains)
 * "~namesel" command to forget previously named selections
 * Autodock Vina tool checks for receptor and ligand hydrogens, adds
  them if missing (previously no hydrogens were added if the user
  chose not to add hydrogens with Chimera)
 * "pdb2pqr," "apbs," and "vina" command
 implementations of the
  respective graphical interfaces
 * support for Gromacs 4.6 trajectories (MD Movie tool)
 * RMF (Rich Molecular Format) Viewer for viewing hierarchical
  structural data and associated restraints from IMP (Integrative
  Modeling Platform, developed by the Sali group, UCSF)
 Animation enhancements and bugfixes:
 * "vseries" command implementation of Volume Series tool
 * "reset" command allows partially restoring a position
 * Animation mouse drag uses left mouse button instead of middle
 * Animation supports custom surface colorings
 * Animation works with volume isosurfaces
 Volume Data (Density Maps, ESP Maps):
 * "measure fieldLines" to display electric field lines for ESP maps
 * "measure mapStats" implementation of Volume Mean, SD, RMS tool
 * "vop threshold" to reassign values below a specified minimum
  and/or above a specified maximum
 * new input format Amira mesh (scalar)
 Enjoy! On behalf of the Chimera team,
 Elaine
