I've been trying to use a kernel file in focal statistics using irregular neighborhood and having no luck. In 10.2 I can't even bring in kernel file manually as it is grayed out in ArcToolbox dialog box. I can it 10.1 but I get the error message, Invalid Irregular Neighborhood Mask (Error 010308), everytime. Is there any work arounds for this? I open up arctoolbox and my kernel file path is lost. My kernel txt file is below.
