Landsat Apparent Reflectance Conversion

Hello,

I'm attempting to process a number of Landsat 5 and 7 images using Apparent Reflectance via the Edit Raster Function. I've made headway as using ArcGIS versions prior to 10.2 failed to read the new metadata file format, but the output is the same indicating that the function failed somewhere (silently).


[INDENT]Method:
Export an RFT file of just using Apparent Reflectance (http://resources.arcgis.com/en/help/main/10.2/index.html#//009t0000023s000000).
Load a Landsat image
Use arcpy to fire Edit Raster Function (http://resources.arcgis.com/en/help/main/10.2/index.html#//001700000163000000) using the RFT filefor Apparent Reflectance on a band of the Landsat image.[/INDENT]

This process completes, but output is identical to the input (no change, this function modifies the input rather than creating a new output).

Attempting to setup a geodatabase to process this imagery seems to indicate the metadata still isn't being read somehow, as the gain & offset are not loaded when the images is added to the gdb.

I have the same result now that I've installed the Landsat 8 patch (http://support.esri.com/en/downloads/patches-servicepacks/view/productid/66/metaid/2012) Anyone have success running this function? I'm beginning to think writing my own python script is the best workaround.
