memory question

Hi everyone,

This may sound a stupid question.

I have 4GB RAM in my desktop running Linux. Can I read in a .nc file
that is 6GB? In other words, I have a netcdf data file that is 6GB,
but I only need one variable in that file. I am wondering when I do:

f=addfile(....)

Does it read in the entire dataset and requires 6GB RAM?

Or, when I do

t=f->T

and t is a very small data array of, say, (100,100), then my 4GB RAM
is large enough?

Please advise. Thanks.

Po-Lun
