Convert NetCDF files to GRASS raster maps

I'm working on converting NetCDF files to GRASS raster maps
by using r.stage3 software package. After compiling the r.stage3
program, I got the problem "UTM is not supported from r.stage3"
when I run the sample netcdf file. Does anyone have experience
on the aspect? please reply this email.

thanks a lot!
