I have converted a polygon file to raster (ArcMap 10.4), after setting extent and cell size environments to match my DEM (which is also set as snap raster). On the new raster, the extents are the same as the DEM EXCEPT for the right (top, bottom and left match). The new raster has one more column than DEM, which prevents me from using it in the model I want to use.

How do I fix this?

Never mind! I fixed it by using extraction tool (by rectangle; the extent of the DEM) on the newer raster. Now, the newest output raster and the DEM have identical extent, columns and rows.
