What's new in Maud 2.9993

Sep 4, 2023
  • The new release fix some bugs for the linear absorption model of TOF neutron.
  • The MTEX model and interface is fully working now.
  • The first implementation of TOF 2D diffraction images using the LumaCam camera has been implemented and deployed.

New in Maud 2.9992 (Aug 10, 2023)

  • Modified the Hippo Wizard by adding some new options for the background. In the parameters list window you can now select to view only parameters that are refinable. Modified also the iterations output to avoid listing parameter values each iteration.

New in Maud 1.999 (Jul 11, 2023)

  • The new release fixes a bug that was slowing MAUD in certain analyses, mainly with texture on multiple datasets and with intensity or angle calibration.
  • Maud.zip: Windows x64 version
  • Maud.tar.gz: Linux x64 version
  • Maud_intel64.dmg.gz: MacOS intel x64 version
  • Maud_arm64.dmg.gz: MacOS arm 64 (M1 or M2 processors)
  • Unzip the files and place the program where you like. Double click the Maud.bat to start on Windows, use the Maud.sh to start the program on Linux. On Mac you get a dmg that you can mount by double clicking on it. Inside you get a Maud.app, copy it to your preferred location. If, when you start it, it says that it cannot be run, open your System Setting of MacOS, go to privacy and security, first you have to enable app not only from the App Store to run, but also from developers, if it is already, just click you want to run the program anyway. Then try to run again the program. If you had to enable from developers, you have to repeat it again.

New in Maud 1.993 (May 17, 2022)

  • The angle conversion routine at the base of all texture, absorption and geometry corrections has been re-worked from scratch.
  • There is a Maud preference to either use the new one or the old one (1.992 and before): testing.useNewRotationMatrices if set to true the new conversion will be used. It is true by default. The angle conversion used is still the one defined in Figure 1 of the paper: Grasslin et al. J. Appl. Cryst. 46, 173-180, 2013.
  • There is one error in the appendix there: in the matrix multiplication not only the Theta matrix should have a minus sign, but also the Eta matrix just after Theta. Otherwise we end up with the wrong rotation as it has been corrected in version 2.992. Please notice that not all rotations are CCW or right ended. But this is what it is in Maud. For the sample the angles are not changing the coordinates system, but adding the angles of rotation. The difference is that of the sign of the angle. So in Maud it is the same sign or rotation as for the goniometer rotations and not the inverse rotation as it should be for a change in the coordinates system of the sample.
  • There is the possibility now to change the background in all the openGl renderings (the rotating 3D figures like the crystallite etc.). You have to edit the Properties.3D file in the maud directory. At the end of the “# Crystallite” section before “# Pole Figure” there may be a line: 0.0 0.0 0.0 0.0 // Background only OpenGl if the line is not there but it ends with “”// Shineness …”, just add this new line for the background. The 4 numbers are the Red Green Blue and Alpha values for the background color. All zeros is for a black background. The maximum value is 1.0 for all 4 and corresponds to white. You have to edit the file before starting Maud. Otherwise just restart it to change the color.

New in Maud 2.992 (Nov 30, 2021)

  • Fixed an error in loading the GSAS parameter file. To fix it temporarily MAUD now loads only the function 1: PRCF1 and ignore the others. There is a second change that concern how texture angles are calculated. There was a mistake in the eta angles tensor that affected the texture angles calculation. To correct it now Maud considers that the eta angle follow a left handed system when viewed from the source as for the others tensors. In most cases this only affected the reference system for the texture, but in few cases (X-ray in reflection with both eta and chi angles different than zero) it it affected also the absorption correction computation. In this version the eta angle is inverted in the calculations resulting in the correct angles calcultation for all cases and a better absorption correction for some cases. But this will change the computation for the old refinements when the eta angle is involved (from the angular calibration to the texture orientation). So to keep the old analysis files still working in this release, Maud also inverts the eta angles set for each datafile when it detects a version of the file older than this release. So your calculation will remain the same. For all the new analyses be careful you may need to redo the calibration also if the eta angles are used, and the texture may look inverted respect to the vertical axis in the pole figures. To check the difference between the old and the new way to compute texture (and absorption) angles, you can switch between the new and old computation using the Maud preference “testing.invertEta”. If it is true the new (correct) calculation is used, false otherwise. Keep in mind that old analyses when loaded from an analysis file will have eta inverted before the calculation (in the angle setting for each datafile) in order to compensate the inversion in the calculation.

New in Maud 2.99 (Jul 6, 2021)

  • A serious bug has been discovered and corrected concerning the polarisation correction. IT affected versions from 2.94 and higher. If you are working with Bragg-Brentano geometry it is advised to update. Go to the download page.

New in Maud 2.98 (Jun 4, 2021)

  • The Hippo wizard has been fixed along with some other bugs with TOF neutron data. To download the new version of MAUD go to the download page.

New in Maud 2.97 (May 12, 2021)

  • In this version the 2D plotting of multispectral has been improved to avoid interpolation over existing gaps in data and showing instead those gaps. Some improvements also to the image integration. There is a new video tutorial associated to this version showing how to work with gaps in images or create some removing data. The video tutorial is available on the Maud youtube channel or here. To download the new version of MAUD go to the download page.

New in Maud 2.96 (May 5, 2021)

  • After long here is a new small update of the program, new Java VM and some bugs corrected. Added conversion of .odeiger image file (exported by Crysalis software) to tiff for proper import in Maud. The conversion is in the ImageJ plugin.

New in Maud 2.94 (Aug 28, 2020)

  • Corrected some bugs related to Lorentz-Polarization correction. Check the readme in the help for more. There are also some minor bugs corrected, so it is advised to download and use this new version.

New in Maud 2.93 (Nov 13, 2019)

  • The new version is out with some bug fixing under the hood. Main one is on strain computation that was accidentally disabled in 2.92. Also the plugins system has been completely rewritten as it was not working properly recently. Check the readme in the help for more. There are also some minor bugs corrected, so it is advised to download and use this new version.

New in Maud 2.8 (Jan 18, 2018)

  • Minor bugs fixing on esg datafiles import to ensure compatibility with old formats.
  • Added a title field to the main window where you can put some comments on the analysis to keep memory.
