I am facing error regarding the execution of maskdata.ulp. Whenever I run the maskdata.ulp, it show some error like maskdata.ulp(51):missing '[' while accessing 'shape'.
I need to copy tstop & bstop layer to the new layer for which maskdata.ulp is used.
Please help me solving the error due to the maskdata.ulp execution.
