Picking out a specific time period from a NetCDF file?

Hi, I have a NetCDF file containing rainfall data for multiple river basins. I only need data for a particular time period (1980-2000) could some body help me pick these out? Thank you.

I have tried the below but I'm met with the error message: The logical indices in position 3 contain a true value outside of the array bounds.

rainfall = double(ncread(fname,'rainfall'));
TIME=double(ncread(fname,'time'));  
TIME2 = double(TIME)/24 + datenum('1800-01-01 00:00:00');
TIME3=datestr(TIME2,0);
years=datevec(TIME3);
from_year = 1980; to_year = 2000;
baseline = years(:,1) >= from_year & years(:,1) <= to_year;
baseline_rainfall = rainfall(:, :, baseline);

1. Read the time data from netCDF file
2. Convert them into datevec, and pick the years you want using ismember or logical indexing.
3. Pick the data using those indices.

Thank you. Could you possibly show me an example?

thanks again

You can try this toolbox: https://github.com/HappySpring/Easy_NetCDF

The following command should solve the problem.

[ out_dim, rainfall ] = FUN_nc_varget_enhanced_region_2( fname, 'rainfall', {'time'}, {[datenum(1980,1,1) datenum(2000,12,31,23,59,59)]}, 'time' );

where {'time'}, {[datenum(1980,1,1) datenum(2000,12,31,23,59,59)]} set the limit for time

and the 'time' follows the above codes indicates that the variable named 'time' should be treated as time.
