Hi Tom and Bill, 

Tom, alot of these problems will go away if you upgrade to the most
current version of GEMPAK which will be using dcgrib2 instead of dcgrib.

dcgrib is not able to decipher the different projections of the ETA run


HDS     ^Y..... KWB. ([0-3][0-9])([0-2][0-9]).*/mETA    PIP

is matching on all the ETA projections, hence the incomaptible file error
as it tries to write a i.e. grid 211 over a 212 etc...


The naming convention I use is: YYYYMMDDHH_eta@@@.gem

the @@@ will be replaced by the grid number wherever they appear,
so they can name the files anyway they want.

However, if they follow my naming conventions, then they won't have
to go modifying all the template files and nmap/garp configurations!


If they only want ETA grid211, then they could change their pattern to
HDS     ^Y.Q... KWB. ([0-3][0-9])([0-2][0-9]).*/mETA

(the Q refers to NCEP's grid #211).

-----------( from Steve Chiswell)

This is not my forte, so if still unclear, i would redirect the question
to address@hidden and Steve Chiswell will be much more versed in
the GEMPAK routines and there uses.

Thank you,
