Showing secondry structural elements with the aligned amino acid sequence

Can anybody help me in using ESPript (http://espript.ibcp.fr/ESPript/ESPript/). I want to show the secondary structural elements with the aligned sequence.

When I upload alignment file in multalign/clustalW format I get aligned sequence in pdf/post script format but whenever I tried to upload DSSP/PDB format along with the aligned file I only get "fatal error".
