nxvalidate used to be a command line tool, but was then replaced by a java GUI application developed by a colleague, but I am working on reinstating a command line version too - I will update you when this is complete. I am not sure of the location of "example.zip", but some test data for nxvalidate is at http://svn.nexusformat.org/definitions/trunk/test/

NXplot was a utility started a few years ago and is available in the "contrib/applications" directory, but is not installed as part of the build. There is a README.build file there, but I have not used the utility myself.

The README is indeed incorrect in your case - it should say that you only need to run autogen.sh if you do not have a "configure" file, which is the case if you obtain a copy directly from the subversion repository; as you have a tar download kit, this includes a generated "configure" and hence excludes autogen.sh

Please share any definitions you develop for neuroscience data with us and let us know if we can be of any further help

Subject: [Nexus] nxvalidate example.zip file; NXplot

I'm trying to learn about the NeXus Format because I think some of it's features may be useful for a project I'm working on, which is to help develop a standard for sharing neuroscience data.

I've installed NeXus on Linux from a recent source, file is:

Now I'm trying to get the various utilities working, which are documented at:

There are two validation utilities described in the documentation: a command line tool (nxvalidate) and a Java GUI program (NXvalidate).

After doing the installation, I found the following utilities in /usr/local/bin:
nexpy  nexus-config  nxbrowse  nxbuild  nxconvert  nxdiff  nxdir  nxingest  nxsummary  nxtranslate  nxtraverse  nxvalidate

The only validation utility is named "nxvalidate" (all lower case), but it's a Java GUI application, not a command line utility as the documentation states.

When I run nxvalidate, inside the GUI, there is a Help menu which includes the following page:

That page states that there is a download available, "example.zip", which contains an example that can be used with NXvalidate.  However, I was not able to find the example.zip file at the location which is referenced:

Question 1) Is there another location where this example.zip file is available, or are there some other sample files that can be downloaded and used with with the utilities?

Question 2) The page documenting the utilities also mentions a utility named "NXplot".  I did not find that in the /usr/local/bin.  Is it, or a replacement, available?


One thing I noticed while doing the installation:  The README file inside the source download directory states:  "2) At present it is necessary to run the autogen shell script to produce the correct configure file.
   sh autogen.sh"

But there is no "autogen.sh" file in the directory.  I assumed that this was an error in the README file, since the autogen.sh file was missing and the installation seemed to work OK without that step.
