Links

These are some links useful for Maud:

  • The Maud forum, new from 6 February 2016 as the one before worked only for a limited time. Sorry for who has spent some time registering to it. Use it to post questions/suggestions/problems working with Maud or in general about the kind of analyses we do.
  • Crystallography Open Database: this could be your main source of crystal structures CIF files. You can search, download the CIF file you need an import them in Maud. Help improving the COD database by uploading CIF structures when you publish one or if you have some you want to share.
  • Full Profile Search Match: this is a new kind of search-match using the Rietveld as core algorithm to search for the phases. It is not based on peaks location, just use only the full profile pattern. This is just a demonstration site, if you want to try it, restrict the number of phases to search by composition. If the search has too many phases to check (more than 5000 typically) the computation may need more than a couple of minutes and the proxy or the web server may cut the connection. This means you will not get a response. We will work around this problem in a near future (may be using emails to send back results not relying on a connection still open).

  1. I want to know where can I find R3c on the list of space-group? It seems that from the pull down menu under cubic space group R3c is missing or do you have a corresponding name for R3c that I am not aware of. Thank you for your kind reply.

    best,

    Jeffrey

    • I just tried now and from outside the University, it works for me. Try it again and tell if it is still not working for you!

  2. In the background function, how can I use the function Set interpolation points manually? That is, the plot windows is open, but how can I select the points? Thank you

    • Jim – did anyone get back to you about the allowed xrd data formats? I have gone through the quantitative phase analysis tutorial and now I would like to analyze my own xrd data, but I’m not sure how to format the file.

    • It is not available at the moment for download.
      In the future there will be a standalone software with it, but probably from a distributor. I cannot say much at the moment.

  3. Furthermore, startlog file says :

    Adding to classpath: lib\swingx.jar
    Adding to classpath: lib\xgridagent.jar
    Adding to classpath: lib\xgridlib.jar
    Plugins dir: C:\Users\ofis\AppData\Local\maud\plugins
    Plugins dir not found!

  4. Thanks a lot for your great tutorials! It is REALLY helpful for me to get started. Would you please send me (kaiyuan0613@gmail.com) the examples in your Quantitative Phase Analysis presentation? The link in this site doesn’t work:(
    Again, thank you for the excellent work! Wish you all the best.

  5. I have used both version 2.33 and 2.8 to refine the same data file but can end up with two completely different lattice parameters, e.g. 0.05A in difference. May I know what is the possible reason for this and which one is more reliable? I also notice that the instruction for batch refinement does not work in the least version of 2.8 due to lack of it.unitn.ing.rista.MaudText.

    • The MaudText (and Maud starting classes) has been moved to another package, it is now in com.radiographema.MaudText
      But the best way to run a batch refinement is now through the “Refine in batch…” command from the Special menu in the Maud interface.
      An opening dialog will appear asking for the location of the script file to run the batch refinement.

      • Thank you very much, Luca! Cannot believe that you reply these in person. I would be grateful if you could attend to the question regarding the difference between v2.33 and v2.8 as well. Or, you may pay attention to that if you have not noticed it yet.

      • Hello,

        I am new to Maud and would like to do Rietveld refinement for multiple X-day diffraction pattern. I would like to run them in a batch refinement. I am not sure how do I create a script file for that?

  6. Hi im having problem with opening the instalation file ( maud.bat ), do i have to do something else, am i missing a step?

    • Check the COD (Crystallography Open Database), there is a direct link from the link page. In the COD website, go to the search page, insert the composition or the name of the MgO phase in the text search (it is periclase by the way) and you’ll get all info you need on the structure.

  7. Hello,

    I have a problem with opening the .bat file from the console. When reading from jar file lib\Maud.jar it always throws the exception: java.lang.ClassNotFoundException: org.sqlite.jdbc
    as well as:
    Exception in thread “main” java.lang.NoClassDefFoundError: HTTPClient.RetryModule

    has somebody had similar problems

  8. Dear Luca

    I found some problems in setting up a Reflectivity analysis using the latest MAUD version. Before installing it, I was using ver. 2.52 and I was able to correctly fit a dataset and to save my analysis. Now I try to load the same analysis with the newer 2.92 version: apart from some minor issues (solved), I can see the dataset but I cannot have the program calculating the reflectivity spectrum. So I tried to buildup a new analysis from the scratch and I get the same result: the program does not compute the XRR spectrum.
    I tried all I could think of, can you please give me some suggestion? If you want, I can send you the old analysis file (which worked fine in the previous version).

    Thank you very much for your generous efforts

    • Click with the mouse right button over the phases tick marks part of the plot and on the instant menu appearing select the phase for which you want the partial plot. It is plotted with no background, so it stays below the total calculated pattern. You can do it for all the phases together.
