Hello, I am trying to calculate the sky view factor index using fish-eye photos. My steps are as follows:
Step1, Rayman pro (Fig.1).

Step2, Input -> sky view factor -> clean the sky and monochrome (Fig.2), then close.

Step3, Output -> data table (or daily data), then table -> act.duration sunshine, and back to the main interface to click "New".
Finally, I can't get the result but the Errors.
