http://www.ing.unitn.it/~maud/feed/MaudRSSfeed.xml The RSS feed about the Maud program Copyright 2005, Luca Lutterotti maud@ing.unitn.it Tue, 6 Sep 2005 10:44:58 CEST Manually by L. Lutterotti Tue, 9 Mars 2010 14:59:13 CEST http://www.ing.unitn.it/~maud/news.html#caen_2010 June 28th - July 2nd, 2010, Caen (France) - Organised by CRYSTMAT and INEL. Maud will be present. Tue, 9 Mars 2010 14:46:58 CEST http://www.ing.unitn.it/~maud/news.html#maud_2220 This is mainly a bug fixing release Anyone using 2.2 must upgrade to this. Several bugs corrected, check the readme. Fixing regards atoms/isotopes selection, CIF importing, background interpolation, sample displacement errors. Superflip method added. Wed, 19 February 2010 19:31:57 CEST http://www.ing.unitn.it/~maud/news.html#maud_2200 Main modifications are: isotopes for neutron diffraction, early qualitative model for fluorescence fitting (use atom concentrations from phases). Check the readme in the help. Wed, 27 May 2009 12:40:08 CEST http://www.ing.unitn.it/~maud/news.html#maud_youtube A YouTube section has been opened where several Maud tutorial as videos are being uploaded. Wed, 17 April 2009 10:57:36 CEST http://www.ing.unitn.it/~maud/news.html#maud_2100 Corrected a bug that prevented to toggle the phases plot on windows. Finished the WSODF method of Popa and Balzar for Strain ODF. Thanks to Sebastien Merkel (http://merkel.ZoneO.net/) for providing his model for strain analysis. Well suited for diamond cell high pressure analyses. You should get a look also to his tutorial pages on residual strain etc. Added the possibility to define/edit manually the background points for the interpolated background. From the interpolated background options panel select the button to edit manually the points and in the appearing plot window select from the menu Tools->edit interpolated points manually the points will appears. Use the right mouse button on them to remove or to add a new one. Only the x coordinate matter for positioning new ones. If you toggle the checkbox to view the background in the plot options, you can see later where the background really is. This new release is named 2.1 for a radical change. There is a new way Maud treats the scale factors/phase fractions. The new way improve the convergence and robustness of the refinement especially in the early stage. In the old behaviour, you usually refine an instrument intensity and all phase fractions apart one (that balance to one and the program take care of doing it). In the new behaviour, you should refine not the instrument intensity, but all the phase fractions (this s done automatically by the wizard). So the program take care of normalizing the phase fractions to 1 at the end of each iteration and to transfer the normalization factor to the instrument intensity. So it is more similar to just refinening phase scale factors internally (like most Rietveld program do), but you end up dealing directly with volume fraction like you are used in Maud. Another advantage is that you can fix the volume phase fraction of one or more phase and the program will keep that fraction constant (this is something not available usually in Rietveld programs). If you deal with multiple datasets, you keep fixed the instrument intensity of the first dataset, but refine all the others instrument intensities (or you can decide initially to refine all the instrument intensities; this will increase the correlation with the phase fractions parameters and the esd or error for them; but you can fix it later when you are near convergences to get better esd on the phase fractions). If you want the old behaviour (because you like it or in certain circustances could be better) you can force it by changing the preference "forcePhaseVolumeFraction.asScaleFactors" to false. Last but not least there is a new model to refine random disordered turbostratic structures like clays or graphites using the Ufer model as implemented in the BGMN Rietveld program (check the web site http://www.bgmn.de for more specific info). This is a very clever way to deal with this kind of structures. The model is called "Single Layer" as Ufer, Kleeberg, Bergman and coworkers named it and you select it in the advanced panel when editing a phase, under the structure factors models. You need a good structure definition for the crstal structure of the basic layer and how many layers you want to generate (Ufer et al. indicate 10 as a good number), then play with the crystallites sizes (may be you need also to use the Popa anisotropic model) to model the line broadening. You don't need to define a supercell, Maud will compute it from the normal cell and the number of layers you select. Wed, 1 April 2009 22:21:12 CEST http://www.ing.unitn.it/~maud/news.html#maud_2075 Corrected and improved the switching to monoclinic 1st setting (or c setting) when working with texture. This is strictly necessary if you are using a texture model like EWIMV/WIMV, standard functions or harmonic based. You need to work in this setting to get the correct texture. It is sufficient to switch to the corresponding space group ending in :c or :c1 whatever and the program will switch cell parameters and atoms (also imported Fhkl lists). Added the possibility to toggle the visibility of the residuals and reflection positions and background in the plot options. Clicking with the right mouse button over the phase label or peak positions in the plot will show a menu that may enable or disable the plot of the fitting for the selected phase. Each phase may plot now its own computed pattern in different color. Tue, 10 July 2008 11:21:12 CEST http://www.ing.unitn.it/~maud/news.html#maud_207 New version to correct a bug on 2.066 causing problems to the least squares routine. Tue, 8 July 2008 23:35:04 CEST http://www.ing.unitn.it/~maud/news.html#maud_2066 Finally Maud is working properly again for texture and structure factor extraction. Now it is possible to have datasets avoiding texture. Tue, 23 Apr 2008 10:31:43 CEST http://www.ing.unitn.it/~maud/news.html#maud_macosx By mistake the Mac OS X versions of Maud where missing some jar libraries. A couple of them are for future enhancements but one is important (swingx.jar). You may notice it is missing as the Wizard frame does not appear when called. I have uploaded new archives of the Maud.app including the libraries. Tue, 2 Apr 2008 15:03:19 CEST http://www.ing.unitn.it/~maud/news.html#maud_2064 The new version includes a version for Mac OS X in 64 bit, but to run it you need an Intel mac at least core2duo and Leopard. Tue, 2 Oct 2007 19:01:46 CEST http://www.ing.unitn.it/~maud/news.html#hippowizard A new tutorial for texture analysis using TOF instruments and in particular Hippo at LANSCE has been added. It explain how to start and perform an analysis having GSAS data as input. Can be used also for other kind of analyses, not only texture. Tue, 2 Oct 2007 19:00:09 CEST http://www.ing.unitn.it/~maud/news.html#maud_2061 Finally after more than 6 months the new Maud version has been uploaded. Mon, 20 Feb 2007 16:57:48 CEST http://www.ing.unitn.it/~maud/news.html#maud_2058 The new version open the Hippo wizard also to other similar instruments arranged in TOF banks. Added a new texture model, the exponential harmonic. It use an exponential function for the ODF ensuring the positive condition. But the pole figure computation method has to be arranged in a completely different way so it is very slowly. Be carefull to use it cause of the amount of time needed for computation. Mon, 20 Nov 2006 22:47:54 CEST http://www.ing.unitn.it/~maud/news.html#maud_2050 The Hippo wizard to help setup an analysis for Hippo LANSCE instrument has been finalized. The refinement wizard also is more Hippo aware. In principle a texture anaysis can be done easily throgh the Hippo wizard to setup it and the refinement wizard->texture analysis to refine it. You have to remember to add at least one phase and choose the more appropriate texture model. Fri, 10 Nov 2006 10:08:49 CEST http://www.ing.unitn.it/~maud/news.html#maud_2049 The new release works well with multiprocessor machines (in the preferences, with parallel_processing.threads_maxNumber you can choose how many cpncurrent threads, equivalent to number of processors to use). An Hippo wizard to help setup an anlysis for Hippo LANSCE instrument has been added to the new analysis menu item. Thu, 24 Mar 2006 8:47:28 CEST http://www.ing.unitn.it/~maud/news.html#maud_committee Some years ago I received an e-mail from Prof. H.-R. Wenk about this. Now I found by casualty even a web page on it. Want to know the hidden history of Maud and the connection to the Los Alamos Lab.? Thu, 16 Mar 2006 11:30:39 CEST http://www.ing.unitn.it/~maud/news.html#maud_forum_poll There are two new polls in the Maud forum. I kindly ask to give your opinion on the question there. You can just vote if you don't want to leave a message. Thu, 15 Mar 2006 21:00:33 CEST http://www.ing.unitn.it/~maud/news.html#maud_qpa2updated The Quantitative phase analysis tutorial has been updated and finished. There are some tips about analyzing the results and plotting. Thu, 13 Mar 2006 21:15:27 CEST http://www.ing.unitn.it/~maud/news.html#maud_forumback The Maud forum has been restored after an hacker attack last fall. Thu, 12 Mar 2006 22:40:38 CEST http://www.ing.unitn.it/~maud/news.html#maud_devexamples More examples has been added in the developer kit. In particular for datafile formats, geometry/Lorentz-polarization correction, angular and intensity calibrations and size-strain models. Thu, 12 Mar 2006 21:39:31 CEST http://www.ing.unitn.it/~maud/news.html#maud_developer A downloadable dev kit and instructions has been added to the Maud web pages for developers who want to build their own models with Maud. Thu, 12 Mar 2006 16:06:52 CEST http://www.ing.unitn.it/~maud/news.html#maud_2044 Some improvements, working on XGrid. Improved the Le Bail structure factor extraction for multiphase analysis. New Simplex algorithm added to the available algorithms. First release of the associate dev-kit to develop Maud extensions/plugins/new models. Thu, 2 Feb 2006 17:39:05 CEST http://www.ing.unitn.it/~maud/news.html#maud_2043 This release correct a bug related to loading multispectra files. Again a system for Xgrid distribute computing has been introduced. It is still under testing, so it is not visible to the normal user for the moment. More information in a near future. Sun, 1 Jan 2006 10:13:34 CEST http://www.ing.unitn.it/~maud/news.html#maud_2042 Happy New Year! Enjoy the new Maud version with bug corrections. Tue, 2 Nov 2005 12:26:22 CEST http://www.ing.unitn.it/~maud/news.html#maud_2037 Minor version, some bugs corrected. Major one concerning computation in batch mode... Tue, 24 Oct 2005 8:40:00 CEST http://www.ing.unitn.it/~maud/news.html#maud_2036 New important Maud version available. Several bugs corrected concerning input/output, GUI panels and plots.
