[gradsusr] reading ASCII data file

[Michael Rawlins]

GrADS does not like the 365 day calendar (see below).  I am processing the data using FORTRAN, thus the desire to map the resultant ASCII data. The processed grid domain, I should mention, is the same as the grid laid out in the netCDF file. 
  

ga-> sdfopen tas_CRCM_1971010103.nc
Scanning self-describing file:  tas_CRCM_1971010103.nc

SDF Error: 365 day calendars are no longer supported by sdfopen.
  To open this file with GrADS, use a descriptor file with 
  a complete TDEF entry and OPTIONS 365_day_calendar.

Hi Michael,

Have you tried reading in the netcdf file using the following instead of 
creating a ctl file?

ga > sdfopen filename.nc
