List-Mode Reconstruction

Dear Castor Users,

I am new to castor! I am trying to reconstruct data from a GATE simulation of the Siemens Biograph Vision PET scanner. I can successfully convert the root data into castor histogram format and reconstruct. However when I repeat the exercise using List-Mode format I get blank images. I would appreciate any suggestions.
