Hi,
    I have installed RegCM-4.1.1 with latest version of Netcdf( 4.1.3). But during pre-processing it stops at terrain making part. It starts smoothly but halts after grid setup, geo-mapping and grid co-ordinate range . Though I have successfully linked all the surface data required through datalinker.py, it compells my wonder why the error comes like this-

"
 Opening /DATA/SURFACE/GTOPO_DEM_30s.nc
 NetCDF library error.
 No such file or directory "

This netcdf data file (GTOPO_DEM_30s.nc) is already in data directory and ncdump successfully reads it.
