I gather that your variable has 4 dimensions. Do you need all those data in core at once? Why not restrict it using the start and count arguments of getvar In my version, it would look like this: data=nc_varget(ncfile,varname,[0 0 0 0],[30 30 30 400]); to get the first 30 longitudes, latitudes and levels, and the first 400 times. Your version will have a similar facility. Read the manual.
You need to think about what you're doing, not just blindly read in stuff you don't need.
Also, don't top post. It makes the thread hard to follow. Put your reply UNDERNEATH.
