.. class:: infomark

**What this tool does**

Estimates the drug-likeness of molecules and reports a score. Comes with three applicable varieties (QED\ :sub:`w,mo`\ , QED\ :sub:`w,max`\ , QED\ :sub:`w,u` ).

-----

.. class:: warningmark

**HINT**

- All invalid, blank and comment lines are skipped when performing computations. The number of skipped lines is displayed in the resulting history item.

- QED\ :sub:`w,max` using the set of weights that give maximal information content

- QED\ :sub:`w,mo` using the mean weights of the optimal 1,000 weight combinations that give the highest information content

- QED\ :sub:`w,u` with all weights as unity, hence unweighted.
