Elena,
thanks for the ncdump suggestion. It mostly works. However, the dimensions are
listed as:
group: \0112 {
group: \0112 {
dimensions:
phony_dim_0 = 224 ;
variables:
double R_pp_2(phony_dim_0, phony_dim_0) ;
double R_pp_4(phony_dim_0, phony_dim_0) ;
I think (although it is not a big issue) that it would be more elegant and more
hdf5-esque to put the actual dimensions into phony_dim_0, e.g.
double R_pp_2(224, 224) ;
Of course it would be a bit more elegant to have h5dump do this, without
requiring netcdf installation.
Best,
Paul
