I am using Raster Calculator in ArcGIS 10.4.1 in order to substract two raster surfaces. However, when I substracted the two surfaces an error 000539 was appeared! I tried to adjust the two surfaces in a specify extent, but clip and extract by mask tools didn't work as I wanted. I tried to fit the first surface into the second one, however, one more column was remained in the former surface. Any suggestion?
