pncopen griddesc file error #135

Closed Lina312 closed 2 years ago

Lina312 commented 2 years ago

When I try the example case "Make CMAQ Emissions from a CSV File", I receive an error about reading the griddesc file (looks like related to the GDNAME) and have no idea why this error happens.

create a GRIDDESC

with open('GRIDDESC', 'w') as gf: gf.write( "' '\n'LamCon_40N_97W'\n 2 33.000 45.000 -97.000 -97.000 40.000\n" + "' '\n'12US1'\n'LamCon_40N_97W' " + "-2556000.0 -1728000.0 12000.0 12000.0 459 299 1\n' '" )

Create a Template

gf = pnc.pncopen('GRIDDESC', format='griddesc')

Error:

I’ll look at making the newer version default to the first. That’s what used to happen. For now, explicitly setting the GDNAM in the pncopen call as shown below. 

gf = pnc.pncopen('GRIDDESC', format='griddesc', GDNAM='12US1')

thanks for finding this.

Does that solve your issue?

It solved. Sorry, I missed this email. Thanks so much for your help.
