The first screenshot doesn't have any of the GP messages (see Geoprocessing>Results) - I would look at those messages and see if you get any clues from them.

I suggest turning off background processing (Geoprocessing > Options > uncheck Enable) and see if that makes any difference.

One more thing spaces and any special characters (besides _) in your pathname may work for most tools most of the time but is not advisable, especially with Spatial Analyst tools.

Dear Curtis

I did uncheck enabling

And the message :

ERROR 010328: Syntax error at or near symbol SPACE.

ERROR 010267: Syntax error in parsing grid expression.

Failed to execute (CreateSignatures).

Any suggest?

Thank you

Best Regards,

Iqbal

You didn't show any of your pathnames used. My guess is you have spaces in your path or raster names.

I was having this exact issue and your guess fixed mine! After changing the output to a folder with no spaces, the process went perfectly. Thanks!
