[gradsusr] Control File for Mask

Jeff,

To answer your suggestions:

-Do fields plot correctly from the first file when it is the only file open?

Yes, the GLDAS file works perfectly by itself.

-Does your mask field plot correctly when it is the only file open?

No, this is the issue I was having actually. I thought changing up some of
the contents of the control file would solve this. Maybe there is an issue
with the mask file. It was produced in ENVI using IDL, but may try to use
CDO instead.

-Check 'q dims' when displaying a field in both files when each is the only
one open. If they are different, that might be a clue as to why the command
you want to run is failing.

Everything between the two files are exactly the same.

-Justin
