[gradsusr] Error

[Guilherme Martins]

Hi users,

When I type sdfopen file, I receive:

ga-> sdfopen UCLM_PROMES_CTL_ERAIN_6H_1990_prc.nc
Scanning self-describing file:  UCLM_PROMES_CTL_ERAIN_6H_1990_prc.nc
SDF file has no discernable X coordinate.
ga->

How may I resolve this? May anyone help me?

Thanks a lot,

Guilherme.
