Hi,
I'm trying to read a netCDF4 variable from a file (no problem) and
then scale it before writing over the original variable in the file.
I'm using python 2.7 and the latest netCDF4 module. It's not that I
keep getting an error message but I want to do this without using for
loops and all the manuals seems to be skipping this task as if it is
never done. I'm new to python and coming over from matlab. Does anyone
know how to modify the netCDF4 variable in python and then write it
back without creating a new variable, or using for loops?
Appreciate the help,
/S
Are you using netcdf version 4, or is that name just a coincidence? If
you're using a 3rd party library, you really should say so, and post a
link, for those curious.
in any case, if you are, I can't help you. This is apparently some
special kind of variable similar to a numpy array.
On the other hand, you may just be asking how to update some bytes in a
file, in place. if you read the file in binary mode, then you can use
seek() to go back the appropriate distance, and simply write it.
