Gembuds, At some point our GARP application stopped listing NAM model grid files correctly - other models seem fine (model plan view button). Everything in Garp_defaults and datatype.tbl are good. The curious thing is that we have some soft links to NAM files that are located elsewhere that are used for case studies. GARP lists those, but does not list the actual grid files (the real-time data) in the same directory. When I remove the links, I get a segmentation fault (probably because it thinks the directory is empty?). Has anyone experienced similar behavior before? Thanks!

I don't really understand what is happening. GARP uses the file /home/gempak/GEMPAK7/ gempak/tables/config/datatype.tbl to tell it where to look for the model fields. It is based off of the "Model Keys", which are defined in /home/gempak/openGARP/build/config/Garp_defaults. First I noticed that you had some dead soft links, which caused GARP to list a mysterious "19" in the file list. I removed the following links: 2012103000 <(201)%20210-3000>_nam212.gem -> /home/dmiller/gempak/grib/2012 103000 <(201)%20210-3000>_narra.gem 2012102912 <(201)%20210-2912>_thin.gem -> /home/dmiller/gempak/grib/2012 102912 <(201)%20210-2912>_narra.gem 2012103012 <(201)%20210-3012>_thin.gem -> /home/dmiller/gempak/grib/2012 103012 <(201)%20210-3012>_narra.gem 2012103112 <(201)%20210-3112>_thin.gem -> /home/dmiller/gempak/grib/2012 103112 <(201)%20210-3112>_narra.gem That did not fix the main problem, however. GARP is finding and listing all of the soft links, but none of the data files that actually reside in that directory. But the GFS directory also has soft links but works fine. When I removed all of the soft links from the $MODEL/nam directory, GARP core dumped, probably because it was trying to build a list from what it thinks is an empty directory. When I put the links back in, it listed the soft links but none of the real-time data. The other models I looked at seemed to be behaving normally. So I don't know what else to try at this point. If you can figure something out, let me know. I will be out of the office until Monday. Sorry.
