Changes in McStas v.2.4.1, June 26th, 2017

McStas 2.4.1 is the sixth release in the 2.x series and fixes various issues with McStas 2.4, plus provides a small set of new developments.


  *   Thanks to all contributors of components, instruments etc.! This is what Open Source and McStas is all about!

Fixes of issues from last release:

  *   A number of issues from 2.4 were corrected, see the relevant GitHub issues for details<https://github.com/McStasMcXtrace/McCode/issues?&q=is%3Aissue%20is%3Aclosed%20label%3A%22McStas%202.4%22%20>


  *   As for 2.4 we the default set of tools are Python-based and developed by Jakob Garde, DTU. The perl ones will stay around as a backup solution
     *   See the GitHub Wiki doc page<https://github.com/McStasMcXtrace/McCode/wiki/User-documentation-for-the-2017--Python-tool-set> for usage
     *   On Unix platforms, the perl tools are accessible by adding .pl to the wanted tool (mcgui.pl etc.)
     *   On Windows, the perl tools are accessible by adding -pl to the wanted tool (mcgui-pl etc.)
     *   BUT: Please use the Python tools and provide feedback rather that sticking with the Perl! :-)
  *   Minor feature developments:
     *   The mcrun utility script now automatically stores a copy of the instr file in the dataset output folder
     *   mcplot-pyqtgraph, mcdisplay-pyqtgraph and mcdisplay-webgl provide the --invcanvas to select white backgrounds in the plots (for now only available from the commandline!)
     *   When installed, the mcstas-clusterscripts package provides an easy way to generate SLURM or PBS cluster batchfiles. The Python mcgui allows to access these via the File -> Configuration menu.

Components and instruments:

  *   MCPL library still at v. 1.1
     *   A minor issue in MCPL_output.comp was fixed
     *   Minor updates to the ESS_butterfly_MCPL.instr, see also: https://confluence.esss.lu.se/display/MCSTAS/Using+MCPL+as+source+term+in+McStas
  *   SNS_BASIS - model of the BASIS backscattering instrument at SNS, from Niko Tsapatsaris, ESS. Further serves as test instrument for two component contributions from the same author:
     *   Spherical_Backscattering_Analyser, a spherical backscattering analyser with variable reflectivity and mosaic gaussian response.
     *   Guide_m, guide piece like the normal Guide.comp, but with independent reflectivity specification for all four mirrors.

Best regards,

Peter Willendrup
