%fullfig  \label{pharmfig}   Pharmacophore as primary query. Each pharmacophore feature has a collapsible menu in the Pharmacophore panel (left)  where its type, location, and radius, as well as number of atoms (for hydrophobic features) or hydrogen bond direction and visibility directionality  (if relevant), relevant)  can be defined. Filters may be set to reduce excessive the number of  hits, by  constraining the number of hits returned for a given conformer or molecule as well as or  the total overall  number of hits. Selecting a hit in the results menu panel (right)  displays it, and its appearance can be adjusted in the visualization menu filter  along with other aspects of the visual display. For example, here the query ligand is shown in light gray, and the selected hit compound is shown in cyan.  This example uses is derived from  tyrosine-protein kinase c-Src (PDBID:  2SRC).
