[ncl-talk] fatal ERROR: Assignment not supported for left-hand type

[Mary Haley]

Francesco,

Your email contained one error message, but the subject contained a
different error message.  I'm assuming that you got both error messages?

I'm not sure what causes this particular error, because I've never seen it
before. If I knew how to reproduce it, then I could probably tell you how
to fix it.

There's not enough information from the code you provided for us to be able
to help.  You will need to examine some variables and provide us with the
output.

Please add the following printVarSummary calls to your code so we can see
what your variables look like:

    printVarSummary(atmMeshmaskT_file->lon)

    printVarSummary(lon1dt_subatm)


There may be another way around this problem. It looks like what you are
ultimately trying to do is convert a 1D array to a 2D array. We have two
functions for this very kind of thing, called "conform" and "conform_dims":

http://www.ncl.ucar.edu/Document/Functions/Built-in/conform_dims.shtml
I think you could replace this code:

    lon1dt_subatm(0:nx_subatm-1) =
(/tofloat(atmMeshmaskT_file->lon(ix_range_atm(0):ix_range_atm(1))) /)
    lon2dt_subatm  = new((/ny_subatm,nx_subatm/),float)
    do iy=0,ny_subatm-1
      lon2dt_subatm(iy,0:nx_subatm-1) = lon1dt_subatm(0:nx_subatm-1)
    end do

with this single line of code:

lon2dt_subatm =
tofloat(conform_dims((/ny_subatm,nx_subatm/),atmMeshmaskT_file->lon(ix_range_atm(0):ix_range_atm(1)),1))
