Dioptas 0.5.3 release

A new version of Dioptas has been released, with a couple of bugfixes and several new features. Notably the ability to load nexus detector files.

The executable versions for Windows, Mac OS X and Linux can be downloaded from https://github.com/Dioptas/Dioptas/releases or here

Anaconda Packages will be made available in the next couple of days and can be downloaded by using “conda install dioptas -c cprescher”.

New features:

  • added a batch integration view (thanks to hard work of Mikhail Karnevskiy @ DESY). Here you can batch integrate your collection series and interact with a contour or 3D plot of the integrated patterns -> this also includes visualization of phases lines
  • reading ESRF hdf5 data files is now possible
  • combined patterns from multiple configurations can now be saved as a file (save button on the upper right)

Bug Fixes:

  • no longer remove integrated intensities below 0, instead now only values with equal to 0 are removed (this should fix all the issues with background corrected images)
  • reimplemented the automatic file recognition algorithm of the autoprocess integration function. This should now work much more reliable also on network drives and linux systems
  • QT high dpi scaling is now only activated for Windows and Mac OS X -> Disabling it on Linux fixes the display bugs encountered here and it is usable with low and high dpi screens (it was not working correctly)

Dioptas 0.5.1 Release

A new version of Dioptas has been released, with a couple of bugfixes and several new features. Notably the ability to load nexus detector files.

The executable versions for Windows, Mac OS X and Linux can be downloaded from https://github.com/Dioptas/Dioptas/releases or here

Anaconda Packages will be made available in the next couple of days and can be downloaded by using “conda install dioptas -c cprescher”.

New features:

  • Phase lines can now be shown in the Cake Widget. Intensity is shown as thickness and opacity of the lines.
  • Phase line parameters can now be copied out of the jcpds widget by using ctrl+c and used directly in your preferred table/text editor
  • Added a Detector Groupbox in the Calibration Widget. Predefined Detectors can now be loaded as well as Nexus Detector files. This enables to load e.g. Nexus detector h5 files which include positions for each pixel. (distortion correction and also useful for combined detector modules not adjacent to each other).
  • Added a Continuous Delivery Pipelines, which automatically create executables for all operating systems (Thanks to Github Actions)

Bug Fixes:

  • having parameters fixed during calibration works now correctly
  • the refine button now also works without automatic refinement and with just a calibration loaded from a file
  • reading trigonal rhombic cif files works now correctly
  • setting the dk/dT parameter now changes the Bulk Modulus of a phase. This parameter was previously ignored.
  • entering the range for the automatic background subtraction works now correctly
  • the motor setup widget is now not showing anymore after starting Dioptas on OS X
  • fixed double logarithm for the intensity distribution display histogram
  • (re)loading of a project with image transformations should now work correctly
  • loading cif files with the newer ‘_space_group_IT_number’ representation work now correctly
  • green line in cake widget is now shown correctly upon reloading dioptas

Dioptas 0.4.1 release

A new version of Dioptas has been released, with a couple of bugfixes and two new features.

The executable versions for Windows, Mac OS X and Linux can be downloaded from https://github.com/Dioptas/Dioptas/releases or https://uni-koeln.sciebo.de/index.php/s/rS4RkVjU6guQeRP

Anaconda Packages will be made available in the next couple of days and can be downloaded by using “conda install dioptas -c cprescher”.

Max Delbrück-Award

My current workplace, the University of Cologne, grants every year 3 “future” awards to individual researchers based on their excellent research activities in the last couple of years. Each of the prices is awarded to a senior researcher, who are usually already Professors, and a “junior” researcher, who are mostly post-doc or Junior-Professors. There are 3 different awards for the different scientific disciplines: the Max Delbrück-Award for Nature- and Lifesciences, the Leo Spitzer-Preis for Humanities and the Hans Kelson-Award for Law and Economic Sciences.

I am the proud recipient of the Max Delbrück-Award for young researchers of the University of Cologne for 2018. Continue reading

New Homepage Online

Finally, the new years resolutions have been working. Welcome to a new version of my personal webpage!

The main intention of the webpage is to have a stage for my research and distribute executables of the programs I have written. I also plan to add some data analysis blog posts later.
