ncread error could not open to read
显示 更早的评论
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.

ncObj = internal.matlab.imagesci.nc(ncFile); 혹시 여기서 다음과 같은 오류가 나오는 이유가 무엇일지 알 수 있는가

Approximate translation:
Error occurred while using internal.matlab.imagesci.nc/openToRead (line 1299)
Cannot open file "C:\Users\MSG\Desktop\jnu_matlab\2017_hycom\GOFS\2017\Monthly\2017\Monthly\HYCOM_201702.nc".
Error occurred:
internal.matlab.imagesci.nc (line 124) this.openToRead();
Error occurred:
ncread (line 71) ncObj = internal.matlab.imagesci.nc(ncFile);
Do you happen to know why the following error is appearing here?
