However this expression fails to include cells that are outside of the ring buffer. I created a new expression which I provide below. </SPAN><BR /><BR /><SPAN>(Con(("%raster1%"&gt; 0) &amp; ("%raster1%" &lt;= 75), .25,&nbsp; Con("%raster1%" == 95, .20), Con("%raster1%" &gt; 95,.05))) / Float(Lookup("%raster1%", "Count")) </SPAN><BR /><SPAN>With this one I am trying to give the cells that are outside of the ring buffers a probability of .05. However when I add my last Con statement I get an error that I cannot seem to fix. I have attached an image of my error. Could anyone please help me solve this. I need to finish this project by the end of the day.</SPAN><BR /><BR /><SPAN>Thank you</SPAN><BR /><BR /><BR /><SPAN> [ATTACH=CONFIG]15968[/ATTACH]</SPAN></BODY></HTML> Wed, 11 Jul 2012 17:49:46 GMT ElenaSava 2012-07-11T17:49:46Z Raste Calculator https://community.esri.com/t5/geoprocessing-questions/raste-calculator/m-p/205664#M7035 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I have been working the following expression in the raster calculator:&nbsp; </SPAN><BR /><SPAN>(Con(("%Prob_horz%" &gt; 0) &amp; ("%Prob_horz%" &lt;= 75), .25,&nbsp; Con("%Prob_horz%" == 95, .20, 0))) / Float(Lookup("%Prob_horz%", "Count")) </SPAN><BR /><SPAN>What I'm trying to do is to assign different probabilities to cells in a ring buffer raster that I have.
