Can I open ClamTK from the linux prompt?

I run Linux Ubuntu without any GUI.  Now I would like to use ClamAV with the GUI. I installed ClamTK on the server but I do not know how to open it. Is it possible to use ClamTK from the terminal? I get thi warning if i type clamtk 

Gtk-WARNING **: cannot open display: at /usr/lib/x86_64-linux-gnu/perl5/5.22/ line 126.
