title: nco extracting data from netCDF with hyperslab
body: <p>I have a netCDF file with ten minute resolution data. I would like to extract the hourly data from this and write a new netCDF file that grabs the data at the top of each hour in the original ten minute file. I think that I would do this with the ncks -d hyperslab flag but I am not entirely sure if this is the best way. </p>
