Hello, I have a netCDF4 file that I downloaded using nccopy and OPenDAP. I want to be able to rename few of the dimensions in that file(read that as coordinate) while retaining the values of the same. I tried using the nco operator(nco version 4.6) specifically the ncrename operator. This is the command that I issued - ncrename -d lat,dimy_D hgt_925.nc and it does rename the dimension. However it removes the values that are associated with lat. I modified the input to ncrename and I tried this - ncrename -d lat,dimy_D -v lat,dimy_D hgt_925.nc. This does give values for dimy_D but it gives them the value as 9.9.2510E36. Short of writing my own program to rename my coordinate variables is there any other utility out there that will help me do the same ? Regards, Ashwin.
