Hi folks -- Has anyone used the NCSA utility "hdfed" to successfully edit HDF files? The documentation on-line from NCSA is pretty sparse, verging on incomprehensible, so I can't tell yet how useful this utility might be. (Any other doc available? ...And/or, if you have experience with hdfed I'd be interested in talking with you.) I'm new to HDF stuff, and have read the IDL documentation on their commands, including HDF_READ and HDF_BROWSER, but those don't work with my version of IDL and the version of HDF files we use here. And even if they did, I'm not sure how one tells one is getting ALL the information in a HDF file, when trying to make simple changes and rewrite to a new HDF file. I'm also going to be needing to generate SUBSETS of HDF files -- with all the global attributes and variables, but with just certain arrays truncated (to focus on a particular range of time, e.g.). I'd REALLY APPRECIATE it if someone could at least steer me toward some good ref.material on how one does these kinds of things (using IDL). Thanks! (The other IDL/HDF commands seem to work OK for me, so I've already written simple IDL routines to edit global attribute character fields, e.g.) -- Joe Jordan (NASA / Ames Research Center jjordan@sky.arc.nasa.gov 650/604-2859 or -6857 (msg.))
