Hi all:

I have been using pymol to load the dcd file before but suddenly something went wrong (either in me or in software) and I can load that traj anymore. I just want to be sure about the command, I am using to load it. 
First i load a pdb file molecule_abc.pdb
then I give command > load_traj molecule_abc, md1.cdc
Its neither loading trajectory nor producing some error or any other message in command line than what I enter.
Could you please correct me ?
