One way to do it (there might be better ways, watch for other responses) is to go to Basic Tools -> Band Math. Enter the expression 'fix(b1)' and hit ok. In the Variables to Bands Pairings dialog box that comes up next, click on B1 if it's not already highlighted, then go down to the "Map Variable to Input File" button, and select the file that you want to convert to integer data. Then choose your output file name and you should be all set. Jeff
