importing .dat binari file including dates and numbers

Hi,

I am trying to import a .dat file which I assume includes a column of dates and several columns of numbers. I am getting errors while trying fread: fid = fopen ('example.ec.dat', 'r') canopy_evaporation = fread (fid, inf, 'unit8');

fid =

    -1

Error using fread Invalid file identifier. Use fopen to generate a valid file identifier.

Could you please let me know how I can import this? Unfortunately the file size is larger than 5Mb compressed, so I could not attach that here. Thanks

Hi Leila,

Please go through the following Stack Overflow discussion regarding invalid file identifiers in MATLAB:

http://stackoverflow.com/questions/10606373/what-causes-an-invalid-file-identifier-in-matlab

As one of those discussion mentions if fopen is used without permission option, or if used 'r' (default) option, fopen will return -1, which is error. Trying using an option like 'w' or 'a' to resolve it.

Hope it helps.

Regards,

Shubham
