1 Replies and 45 Views IDL FREE_LUN error  45  1 Started by  Drew Ciampa I have a script that loops over a function that opens different files and reads their contents. At its root, the function is utilizing FXREAD.PRO to read the FIT file. On about the 200th iteration the script stops with the error... FREE_LUN: Error closing file. Unit: 100, File: /PATH/TO/FILE Bad file descriptor I'm guessing this means that the LUN assigned for the opened file is not being closed properly and a open unused LUN is not available Since I was using FXREAD.PRO I figure...

0 Replies and 30 Views How do I use IDL to differentiate between NetCDF-4 and NetCDF-3 files?  30  0 Started by  Jim Uba Q: An IDL user asks: How do I use IDL to check the type of an NetCDF file, for example, NetCDF-4 (HDF5) or 'classic' (NetCDF-3) A: As of IDL 8.7.2, IDL doesn't have a simple built-in routine to distinguish between NetCDF-4 and NetCDF -3 files. However, custom IDL code might allow this, for example: ; <...> file = '' print, '>>> File: 'file ; All NetCDF-4 files are HDF5 (but not always vice versa) if H5F_IS_HDF5(file) then begin pri...

0 Replies and 27 Views How to display an image that sets the data ignore value  27  0 Started by  hua li Hi , I clipped an image using a vector and added ‘data ignore value = 0’ to the header file. It is correct when displayed in envi but still has black borders in IDL. I don't know how ‘data ignore value’ is handled by envi. Is it saved as NAN What function should I use to display an image with no black border in IDL Or how do I deal with the value 0 in the array that should be ignored

(I know it is possible to make isosurfaces in direct graphics, but that will not solve our current problem.) Thanks, Ken Bowman
