I get the following error while trying to access the nc file. If i get into the folder and try it directly ncread works, but I need to use it in a for loop for a number of similar folders. Any ideas why I get this error?

 Error using internal.matlab.imagesci.nc/openToRead (line 1259)
  Could not open /sw-test-1-1-141-r28/cpd.nc for reading.
Error in internal.matlab.imagesci.nc (line 121)
                    this.openToRead();
Error in ncread (line 53)
ncObj   = internal.matlab.imagesci.nc(ncFile);

I was able to get the same error message. Try to remove the first '/' from the filename passed as input argument to the 'ncread' function. If I have a demo.nc file in a folder called 'ncfile', my command would look like 'ncread('ncfile/demo.nc',varname)'. I hope this helps.
