Hi,

My matlab is R2020a, i want to create a large netcdf file (>2GB) with 64bit format, however, when I set :

ncid= netcdf.create(filename,'64BIT_OFFSET'); or netcdf.setDefaultFormat('NC_FORMAT_64BIT'); , I met the error:

netcdf is meeting error when excuting 'putatttext' library- 'operation not allowed in data mode (nc_enotindefine)

when I change the format to 'NETCDF4', it worked, however, I expected the format to be '64bit', do you know how to fix it ? thanks a lot

Hello,

ncid= netcdf.create(filename,'64BIT_OFFSET') gives me normal result without error.

Could you provide more code and more error information?

Hello,

I have tried the netcdf.create function in R2020a. Seems to work fine for me.

Request you provide the program along with the specific error message, that might help me reproduce the issue at my end.
