Re: addfile and HDF5 library version mismatch

Hi Madeline,

My sincere apologies. I responded to this on Friday (I think), but either I forgot to hit "send", or it just never got sent.

In my response, I asked you to run this sample test script and let me know what happens:

  filename = "test_nc4.nc" ; name of netcdf 4 file
  x = random_uniform(-100,100,(/10,64,128/)) ; dummy data

  if(isfilepresent(filename)) then
    system("rm " + filename)
  end if

;---Open netCDF-4 file
  setfileoption("nc","format","netcdf4classic")
  fout = addfile(filename,"c")

;---Write to netCDF-4 file
  fout->x = x
  delete(fout) ; Close the file

;---Read variable back in
  fin = addfile(filename,"r")
  xin = fin->x

  diffs = xin-x
  print("min/max diffs (should be 0) = " + min(diffs) + "/" + max(diffs))

On the UNIX command line, if you type:

     file test_nc4.nc

It should say something like:

test_nc4.nc: Hierarchical Data Format (version 5) data

Let me know if you have any luck with this.
