Does anyone happen to know if the subset data selection tool and the way it reads how many subdata exists in a raster dataset has changed between 10.2 and 10.3. I am working Climate Data that has multiple rasters in a raster dataset. When you view the same raster data set in arcmap 10.2, there are 769 rasters in the hdf file, However if the same dataset is opened in 10.3, there appears to be 5297 subdatasets. For some reason in 10.3, the same subdataset is appearing multiple of times which did not happen in 10.2. In the attachment, you can see the same subdataset appearing multiple of times. I am not sure if this is a bug or not.
