<p dir="ltr">The link that Gavin refers to provides information on doing STM simulations using MATLAB; the lapw2STM code is only for large biases (insulators) and even then probably not needed.</p>
<p dir="ltr">as Peter's email hinted, a simpler method will be in the next release.</p>

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

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

> I am interested to know the detailed procedure of simulating STM images in wien2k. 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”.<br>
