Error reading NetCDF files

Hello! I'm trying to read a NetCDF file using this:

f='global.nc';
fid=fopen(f,'r');

Temp=ncread(f,'t');
U=ncread(f,'u');

but it shows an error message, something like this:

Error using netcdflib

The NetCDF library encountered an error during execution of 'inqFormat' function - 'Not a valid ID

(NC_EBADID)'.

Error in netcdf.inqFormat (line 29)

fmt = netcdflib('inqFormat',ncid);

Error in internal.matlab.imagesci.nc/openToRead (line 1281)

this.Format = lower(netcdf.inqFormat(this.ncRootid));

Error in internal.matlab.imagesci.nc (line 121)

this.openToRead();

Error in ncread (line 53)

ncObj = internal.matlab.imagesci.nc(ncFile);

Any ideas of what is going wrong! Thank you!

Hey

can you show me this:

ncdisp(f) 

results?

I think you want to open temperature and wind speed in this netcdf file.

filename = 'global.nc'
temp = ncread (filename,'t');
wind = ncread (filename, 'u');

To list the variables:

filename = ('global.nc');
info = ncinfo(filename);
{info.Variables.Name}'

neither ncinfo nor ncdisp work.. i think it's something with the library but i dont know..

Dear Thodoris,

Please make sure the global.nc file exist in the current folder section of matlab:

after you sure about it try using this code below then show us what is the outputs:

filename='global.nc'; % exact Name of your netcdf file
ncdisp(filename) 

also I want to know what is the version of your Matlab?

[Thodoris Ptrks]

yes i have set the direction folder from the beginning and imported the file... it crushes with ncdisp or ncread and all nc commands... i have 2018a version

I think maybe your NetCDF file is corrupted. can you open the attached NetCDF file which I sent to you?

[Thodoris Ptrks]

no.. by the way thanks for your time..!
