What coordinate system is your measured data in? The default data format( if I am not mistaken) for the BSDF data in Radiance is the LBNL Full Klems format i.e there are 145 x 145 values for incident and exitant radiation.
A while ago, I had written a python script for reading BSDF XML-files (see attached). The SingleClear.xml that you posted above will read
something like :
Do the values that you have for your film match the 145 x 145 format corresponding to the LBNL Klem’s full basis format?
Here are a couple of other links related to measuring and incorporating BSDF in Radiance:
I am not sure if you can simply convert data from one format to another. The values that are found in Window 7.4 correspond to measurements made through a photogoniometer: http://www.pab.eu/gonio-photometer/
The values that you saw in the image are radiation values from the BSDF file. The file that you uploaded actually is already in compatible format.
