Hi All

Would be great to have access to this functionality.

allmost unbelievable that this functionality does not already exist - absolutely necessary for descriptive statistics.

The Percentile Option should also be added to Focal Statistics tool.

Hi Xander,

I've been using your python script to do this for two years now and it has always worked great. Until today when I tried it on a 32 bit signed integer raster I can't get passed this error:

Traceback (most recent call last):
File "C:\Python27\ArcGIS10.3\Scripts\percentilesTrinityWY16_bymask.py", line 140, in <module>
main()
File "C:\Python27\ArcGIS10.3\Scripts\percentilesTrinityWY16_bymask.py", line 79, in main
dct = {row[0]:row[1] for row in arcpy.da.SearchCursor(outname, flds_ras)}
RuntimeError: cannot open 'ras1'

Failed to execute (TrinityPercentilesbyMask).

It seems as though this is being caused by the temporary 'ras1' not having an attribute table.

Any thoughts?

Thanks

Brian

It runs fine with a 16-bit raster but not a 32-bit raster, so I had to scale my values to 16-bit. Anyway to get it to work with 32-bit?
