ncx, NetCDF eXplorer

Interface for NetCDF visualisation

Description

NCX is an interface (GUI) for NetCDF visualisation. NCX already includes the Matlab/NetCDF interface for Matlab versions from 5.3 until the current release 14, for Windows and Linux (authors: Charles R. Denham and John Evans)

For a tuturial see the site:
http://www.odyle.net/mma/archive/ncx/

Installation:
-Unpack and add the base older (ncx) to your matlab path
-execute ncx at matlab prompt

• MATLAB release: MATLAB 6.0 (R12)

[d dd]

tried several nc files, doesn't work

[M MA]

Humm... thats strange. It works fine with me and many people arround the word... hope I can help

[X Y]

I just need to convert my .nc file to a text format so that it becomes readable...Can someone help me??

[Alex AK]

nice and easy tool

[Wang Yanlei]

convenience and availability

[Panos Athanasiadis]

The tool is great. Now while working in MATLAB you only type <ncx> and see what is in your data .nc files.

There is space for improvent however:
----------------------------------------
a) It would be easy for the program to also plot anomalies along the chosen axis.

b) Ideally it would be nice to be able to play a sequence of frames.

c) Finally, I could not make it to plot lat-height or lon-height cross sections.

[Mathew Owens]

Saves the hassle of installing netCDF and MexCDF on Linux - what a blessing!

[Ani Suryani]

Very good, I hope this inteface can be used by all of oceanographer in the world..
Request for explaination :
could you please tell me, it is possible or not to run ncx on Matlab 7.1 R14?

[Usama Anber]

Plz can some help me, I used this ncx to load a netcdf file from the IPCC website (output of a GCM for air temperature), but it didn't work, what should I do ?

[Mark Brandon]

The support files for this program needs to upgraded to work with Matlab 2009a. You will need to get the latest version of the mexcdf package, which is available at sourceforge, at http://mexcdf.sourceforge.net/downloads/R2008a.html. Just replace the files in the mexnc and netcdf subdirectories with the new files in the subdirectories with the same names in the mexcdf package. Matlab now provides native support for netcdf files, so there is no need to generate dll or mex files. Everything will work just fine.

[Vengatesan]

This is the first time i have downloaded and installed ncx on a windows xp machine with matlab R2007a. After typing nxc it displays the GUI, but upon loading a file the following error message comes up. any help?
>> ncx

[David Schneider]

Does anyone know what the scripts in the /private directory are for and why it's named as such? Private directories are not allowed in the Matlab path, so how are the scripts in this directory to be used? Thanks for your help - seems like a great program so far.

[janez]

i'm running Matlab R2008a and cannot get ncx to work. when i try to load the file, i get the following error:
??? Error using ==> feval
Invalid MEX-file 'C:\Program Files\MATLAB\R2008a\work\ecomviz\ncx\netcdf\mexcdf\pcwin\mexcdf53.dll': C:\Program
Files\MATLAB\R2008a\work\ecomviz\ncx\netcdf\mexcdf\pcwin\mexcdf53.dll is not a valid Win32 program.

i tried to do what Mark Brandon suggested above but i cannot find mexcdf53.dll file in the latest sourcefourge directory and the error keeps repeating and the ncx doesn't work.
it's such a tease!
any thoughts anyone?

i tried substituting
