I'm trying to run batch simulations for N-S single axis trackers with a tilt of zero.  All I want to do is vary the pitch.  In the Parameter Specification, 3D shadings parameter I select Pitch E-W between trackers and backtracking activated.  I did notice that the parameter word "Backtraked" had been misspelled in the output file. I get the message:  Warning: The shading table has not been computed in the results I ran this in batch mode with just one data point for the pitch: PVsyst simulations Batch mode;;					 Simulation parameters and results;					 File Created on 01/11/16 10:24;;					 ;;					 Project ;;;Sample PVsyst;;					 Variants based on;;VC2;ATI_Duratrack_HZ 2.1 MW DC;;					 ;;					 ;;					 Ident;Trackers;Backtraking;Simul;Error;E_Grid;					 ;Pitch EW;;Comment;;MWh;					 ;[m];Y/N;;;;					 ;					 SIM_1; 4.00;Y;ATI_Duratrack_HZ 2.1 MW DC ;Warning: The shading table has not been computed;4082; Thanks for your time, Mike Reed
