Maybe "Appendix A. STM Image Simulations: Theory & Implementation" in 
the dissertation by one of Prof. Marks students at the following link is 
of interest to you:

However, I don't know if the lapw2STM code is available to the public.

I did some research on google, and learned that the key quantity to be calculated is the partial charge density in a given energy range. This range is defined by the bias voltage of the simulated STM measurement.  The command to be issued is “x lapw2 -emin V_bias”.
