Windows64 Instructions

First extract everything from the Maud.zip you downloaded. You should get a Maud directory with the following structure:

  • maud.bat (to start Maud))
  • Maud.jar
  • lib (directory)
  • licenses (directory)
  • plugins (directory)

Move the maud directory with all the content in the place you are more comfortable with. Be sure you have the rights to write in that directory.
Start Maud by double clicking the maud.bat (Do not start Maud double clicking the Maud.jar, even if it may start, it will not be fully operative!).
The first time Maud run, it will show the license agreement window and after you press the OK button it will show a dialog asking for a directory where to extract some files. These are files needed by Maud (databases, preferences etc. plus some examples) and to avoid to pollute your Maud directory it is advised to create another directory (it can be located inside the Maud one, we will call it the examples directory in the following). Be sure to enter inside the newly created example directory before pressing the Extract here button.
To check everything is ok, from the File menu, choose Open analysis… and choose the alzrc.par file inside the example directory. After loading it, press the calculator button in the toolbar to calculate the pattern. You should see a nice fit of the data with the residuals. You are set and ready to use Maud. If not check the troubleshooting section.

Tips (before or after installation)

  • How to check if you have a 32bit or 64bit java VM installed:
    Open a command prompt window. In Windows 8 you can find it from the Start window, in the down screen Apps by name under Windows System (first entry). In Windows 7 and before from the Start menu choose run command and type cmd.exe. In the command prompt window type:
    java -version
    and check on the line starting with Java Hotspot if it written 32 or 64bit. If java is unrecognized as a command, you have the same problem as described in troubleshooting Case 1. Use the full path to specify the command.
    In general if java is installed inside Program Files it should be 64bit, if it is instead inside Program Files(x86) is 32bit.
  • If you have some troubles starting or running Maud and nothing you do can solve it, check first you have a startingLog file in the Maud directory. If there is not this file you don’t have java installed or the maud.bat cannot find it, check the troubleshooting section. Otherwise you can send it to the Maud author for help along with the content of the Maud console if you can reach the Maud main window.
  • How to activate the Maud console and get more output, info and errors reported: when the Maud main window opens, select console visible from the Interface menu.

Troubleshooting
If something does not work, be sure your java virtual machine is properly installed and working and that you didn’t have a corrupted download of Maud. Re-downloading it sometimes solves the corrupted download problem. But be aware of proxy caching the downloads, it means that if the corrupted download is in the cache of the proxy server, you will download again the same corrupted archive. Changing network for the download or forcing a refresh and download 1-2 days after may solve the caching problem.

  • Maud does not start using the maud.bat.
    Try double-clicking the Maud.jar: if Maud starts, then you have a proper java installed, click cancel on the license agreement window and proceed with I have Java; if Maud does not start, install java from the official website, then try again with the maud.bat
  • I have java but Maud does not start.
    There are two possible problems and for both you have to edit the maud.bat by right clicking with the mouse on it and choose Edit from the menu. The maud.bat has only one line containing the following:
    java -mx4096M -cp Maud.jar;lib/ij.jar it.unitn.ing.rista.Maud
    The first word, java, invokes the java virtual machine, then -mx4096M specify the maximum memory java can use for Maud (4Gb in this case), the -cp specify the classpath for Maud (the jar libraries to use) and finally it.unitn.ing.rista.Maud the starting class (that is contained in the Maud.jar). So the possible two problems are:

    • Case 1: java is not a recognised command. You need to add the full path to maud.bat. So first locate in your computer where java.exe is installed. Typically in something like C:\Program Files\Java\jre7\bin, copy the path (by clicking the mouse in the Explorer toolbar after the end of the path field to select it, it will transform in a traditional string with the path elements, and then you ctrl+C to copy to clipboard) and paste it or write it before the java command in the maud.bat. Add the double quote before and after java if the path contains some white spaces. You will end up with something like: C:\Program Files\Java\jre7\bin\java -mx4096M -cp Maud.jar;lib/ij.jar it.unitn.ing.rista.Maud. Save maud.bat and try again to run maud.bat by double clicking it. If it still does not start check Case 2
    • Case 2: the maximum memory specified is more than what your java virtual machine can support. You may have a java 32 bit VM installed, so the maximum memory usable by java is between 1.2 and 1.7 Gb depending on System configuration and loading. Edit the maud.bat file and change the -mx option to -mx1024M to check if the memory is the problem. If it works you have installed a 32bit java VM. This happens typically when you download java using IE from the Desktop environment in Windows 8. If you want the 64bit java VM, use IE from the Start screen on Windows 8, or in the Java web site specify you want to choose the java VM to install and then choose the 64bit jre (Java Runtime Environment).
  • Maud start, but you are not able to arrive to the Maud main window.
    You may have either a Java VM not working properly or a corrupted Maud installation, in either case try to re-download one or the others or both and re-install them. Otherwise, check the startingLog file created inside the Maud directory when Maud starts and in case send it to Maud author. Check the Tips section for more.

    Dear office holder,
    Sorry to trouble you! We meet the last problem on windows 7 64bit platform. The problem is “Maud start, but we are not able to arrive to the Maud main window.” The java is OK.

    I have a problem in using this software. Can you offer the preferences about the microstructure model of polymer single chain. Thank you!

    i have the same probleme as “Yanhui Wu”

      For the problems starting Maud, if you are not able to sort them out based on the troubleshooting section above and tips, post here or send the author the startingLog file. If you don’t have it check more carefully the troubleshooting…..

    Hey,

    I have the same problem as wafia. I download Maud and java but still can’t get to the main window.

    Thank you in advance for your help.K

      Have you tried the last version?
      A version 2.63 or higher. In the new Maud beta, the Java virtual machine is included, so there shouldn’t be anymore problems related to the Java version etc.
      But it is mandatory to start Maud by running (double clicking) the file Maud.bat and not the Maud.jar, because if you double click the Maud.jar, it will use the Java installed on your machine and not the one embedded in Maud. So you run into the same problems as before.

      In a future release I will remove the Maud.jar and move it to the lib directory, so I hope nobody will click anymore on it to run Maud.
