I'm trying to run batch processing files written in IDL from the SeaDAS 6.3 command line (with a full IDL license), but "seadas -b filename" just results in "The command file filename does not exist. Exiting." I've placed the files I'm trying to access in the SeaDAS idl_lib directory, but that hasn't solved it.
filename should be the name of the file that contains the commands. What SeaDAS is telling you is that it can't find a file called "filename" in the working directory. You do not need to put these files in idl_lib (and probably shouldn't, although it really won't hurt).
