Target Raster for Mosaic Tool doesn't show up

Discussion created by merebears on Jan 15, 2014
I am trying to run the mosaic tool where I put in one raster as the input raster and another as the target raster.  However, both of the rasters I want use show up as options for the input raster and nothing shows up for the target raster.  Neither raster is showing up in ArcCatalog even though they are both displaying in ArcMap.  Anyone have this issue before know what the problem is?
