How can I write a variable which datatype is a string in netcdf file

Hello, Im new using Netcdf files.

I need to write a variable which is a string in a netcdf file.

I tryied this:

nccreate(file_name,'/dataset_ambient_noise/calibration/calibration_procedure','datatype','char','Dimensions',{'hydrophone_count',hydrophone_count}); %to create the variable calibration_procedure

and then I used ncwrite to write the variable:

ncwrite(file_name,'/dataset_ambient_noise/calibration/calibration_procedure',calibration_procedure);

calibration_procedure is equal to a string (no matter what).

When I do this I get the error:

"The NetCDF library encountered an error during execution of 'putVaraText' function - 'Start+count exceeds dimension bound (NC_EEDGE)'."

Does anyone here can help me??

Thanks in advance.

Most likely, the space you specified for the variable calibration_procedure in the nc-file, i.e.

'Dimensions',{'hydrophone_count',hydrophone_count}

is too small to store the value of the Matlab variable calibration_procedure

That is

length( calibration_procedure ) > hydrophone_count

is true
