New Endeavour Version 1.8

October 11, 2018

A new version 1.8 of Endeavour, our software for crystal structure solution from powder data, has just become available. The new version contains several improvements and a variety of bug fixes:

  • Crystal structures containing molecules/rigid bodies can now be solved directly in a space group other than P1, even if their atoms must be placed on special positions.
  • The design of the user interface has been polished.
  • The Multiple Document Interface (handling of more than one structure document at a time) now has a tabbed interface.
  • The structure solution progress graphics now appears in a docking window, displaying graphs for multiple seed values and/or documents at a time.
  • Display of overall cost function in addition to R-factor in progress graphics.
  • A new HTML-based online help system replaces the outdated (and not more supported under Windows Vista through 10) "Windows Help" system.
  • One single manual and tutorial file containing the (now obsolete as separate PDF files) "Endeavour Kernel Scripting Reference", "File Formats", and "Quickstart Tutorial", cf. "Help/Manual and Tutorial".
  • The latest settings (when you close Endeavour) are now stored in the Windows Registry (HKEY_CURRENT_USER\Software\Crystal Impact\Endeavour) rather than in the "Endeavour.ini" file in the "C:\Windows" directory.

In addition, a variety of bugs has been fixed:

  • "Failed to launch online help" message: The outdated online help system basing upon "Windows Help" (Endeavour.hlp) has been replaced by a new HTML-based online help system (Endeavour.chm).
  • On some Windows 10 systems, Endeavour crashed when you clicked into a row, e.g. in the table of atomic parameters or in tables in several dialog windows.
  • Weakening of the repulsion between two neutral atoms, if their distance was smaller than the minimum distance.
  • Swapping of positions of rigid bodies was permitted even though they were fixed to a certain position (being only allowed to rotate). As a result, it looked like originally fixed molecules were moving.
  • When you changed between different configurations (e.g. "Select configuration" command in the configuration list context menu) and some of the atoms had S.O.F. < 1, these S.O.F. were not copied to the current structure parameters (i.e. appeared as 1 in the atomic parameters dialog, for instance).
  • Results Report was not updated correctly when changing between configurations.
  • Export of diffraction data in Ihkl format wrote Fhkl rather than Ihkl values into the output file.
  • Several minor bugs have been fixed as well.

Endeavour users should use the online update function (menu "Help/Online update") and/or check our Endeavour Update page.
