CDFx is an IDL software tool for displaying, editing, and listing the contents of CDF data files. It displays image plots, time-series plots, CDF variables; it will list and store CDF data in plain ASCII text; and it will save subsets of data to new CDF files.
Familiarity with CDF and ISTP CDF conventions will be helpful when using CDFx. ISTP specifications and master CDF file concept discussions are at the SPDF Use of CDF site. General discussion of the CDF data format can also be found on the CDF site.
CDFx is a part of CDAWlib and requires that RSI's IDL, versions 5.3 and above, be installed on your local system. (IDL version 6.2, especially on 64-bit platforms, will probably not work.) IDL6.3 and newer versions, both 64 and 32 bit versions should work, but require the fixes to the CDF API s/w which are available from the CDF site: http://cdf.gsfc.nasa.gov/, specific information is at http://cdf.gsfc.nasa.gov/html/idl62_or_earlier_and_cdf3_problems.html It is not necessary to compile or run any of CDAWlib's other tools in order to use CDFx.
After downloading and installing CDAWlib, and after following the General Instructions in CDAWlib's on-line help, CDFx should be ready to run. Launch an IDL session and enter the following commands (displayed in boldface):
% Compiled module: VERSION.
% Compiled module: CDFX.
You should now see CDFx's main menu window, which will remain on your desktop throughout the CDFx session.
This section demonstrates a simple CDFx session that illustrates some of the software's key features.
