Welcome to Jaques 2.0 Even after 12 years Jaques remains a quick hack, as I've been learning how to use the IDL widgets and basically most features of IDL. So sorry for the mess. However, it is useful. I hope that the use of Jaques is worth an acknowledgment in the scientific papers and talks you use it for. 1) What is Jaques ? It's a whole bunch of IDL routines to visualize multiple mesh data. Jaques is enzo's best friend. 2) How to install it? From the SVN repository: svn checkout http://svn.enzotools.org/jacques/ in the trunk directory you find all the relevant start up scripts etc. cd trunk doit is a simple shell script to set one environment variable and start up jaques. clean and install are also trivial shell scripts. You can set some favorite startup values of variables in your home directory using a ~/.jacquesrc file. An example is included in this directory. cp jacquesrc ~/.jacquesrc 3) How to run it? simply type: ./doit if you do not have an idl license available and do not need access to the command line for what you're doing you can also run ./start-vm.sh which will run the program with the IDL virtual machine. 4) Problems ? There are many many possible situations the tool will crash. FIX: type retall or @tools.com and you should be able to try again Please make sure that the hdf4 command vshow and the hdf5 h5ls and h5dmp commands are in your path. These are used to speed up the reading of data. 5) Check out the WHATSNEW and BUGS files of the distribution. In particular the WHATSNEW file gives hints of what jaques can do for you.
