+<em>i.oif</em> calculates the Optimum Index Factor for LANDSAT TM bands 1,2,3,4,5 and 7.
+<p>
 The Optimum Index Factor is calculated to determine the band combination which
 shows the maximum information when combined into a composite image. The bands
-comprising the highest scoring combination from <EM>i.oif</EM> are used as the 
-three color channels required for <EM><A HREF="d.rgb.html">d.rgb</A></EM> or

 The analysis is saved to a file in the current directory called "i.oif.result".
