iso cluster unsupervised classification ArcGIS 10 Windows XP

I was attempting to run the iso cluster unsupervised classification routine in Arc10, SP1, Windows XP. I have a small 6 band landsat image subset (~1 Mb) Imagine file that I am using as an input. I choose 10 classes to be created, create an output Imagine file to c:\temp, and take the defaults and create a spectral signature file. All are going to c:\temp. The iso cluster unsupervised classification bombs. If I import the image to a file geodatabase, and use the file geodatabase image as the input it works, even if I choose to create an Imagine file output. It looks like my input file cannot be a file based image format (Imagine, TIF, etc). In the results tab, it looks like the process does not seem to create the output file or the .GSG file.

If I do the same operation on Arc10 in Windows 7, 32 bit, I can run both an Imagine file or a file geodatabase raster data set as the input.

I don't know if this is a bug or something else going on. Any insight would be appreciated.
File is attached.

Thank you,
Nate

Nate,

I just saw this post after I sent the email. Moving the raster into a filegeodatabase solved the problem. How you figured that out I don't know.

Thanks,

Jeff

I also just had trouble running this tool. I'm working in Citrix with ArcMap 10.0 and tried running the tool on 3 bands from a Landsat 8 file. I would get a result, but it would be warped, as if in a funky projection, and have striping. Landsat 8 doesn't have any data gaps to result in stripes. The result just didn't make any sense. Yet, I put the file into a Personal Geodatabase and the classification then looked just fine. Thank you for this tip!
