I have a trouble with getting pixel count on the attribute tables.
The below is what I did
1) Download USGS imagery (glovis.usgs.gov)
     Downloaded like follows

2) Raster Processing -> Composite Band Function Create Composite Image
     (Follow the Link below: http://www.uvm.edu/~joneildu/Video/GIS_Open/LandsatArcGIS/Landsat%20ArcGIS.html)

3) The view looks fine by RGB=321 or RGB=432 etc, I clip the image.
   (I follow the supervised classification, following the instruction the esri book: Using GIS and Remote Sensing Workbook)

4) After I classify by supervised classification and export the data, It prompt to pixel depth and I clisk yes

5) The resulted attribute table looks very strange.

    Is this something wrong with data?

Ok, My question now is,
Is there any way, I can get the pixcel count from here,
If not, what is wrong (Seems to be original raster data?)? and how to fix it.
