Classification tools

Hi,

I am using ArcGIS Pro 2.0.1 to perform a supervised classification. After going through the process, I further modified the output raster by combining with other rasters to add additional attributes to the table (elevation, slope, aspect, etc.).

Now I would like to be able to regain access to the reclassifier tool to take care of some problem areas. Unfortunately, I can't access the reclassifier tool with this raster selected. I can see the tool if I go back to an earlier version of the classified raster so I am assuming there is something about the raster characteristics that does not allow me to use the reclassifier tool anymore. Can someone explain to me how I can use the reclassifier tool on a raster that was produced by the image classification wizard, then further modified using the raster calculator? For example, does the raster need to be 8 bit in order to use the reclassifier? Or is it the format that matters?

Thanks!

Oh boy, I think I figured it out. I used arccatalog to change source type from generic to thematic and now I can see the reclassifier tool!

Quick follow up - how would I make that change within the arcgis pro environment?

haven't tried, but most things in Pro are tool bases... like
