Hi, I am Vamseedhar Rayaprolu (Vamsee). I work with viruses and I am trying to generate a movie using only a script and NO GUI. I use a viral protein from the VIPERdb and hence it automatically generates a multimer (capsid) for me. The underlying question is 2-fold. The model generated from a vdb file is a pseudo-model and doesn't carry any co-ordinates for each of the subunits. Therefore the whole model is numbered #modelnumber (#1 in this case). The capsid has 60 subunits and when I mouse-over onto each of the subunits, it shows me the model number and the sub-model number but when I try to access the sub models through the command line, it selects #1 as a whole and not the sub-model. I need to be able to select each sub-model through the command line. Any ideas on this? Next, I need to be able to show each sub-model in a ribbon form. Trying to show the whole model (#1) in the ribbon form using a command doesn't work. It works when done from the GUI though. I know if I can split the above multimer into sub-models I should be able to use the ribbon command and get what I need. But the split command doesn't work on the model as there are not atomic co-ordinates (pseudo-model). Any suggestions on this? Thank you -Vamsee
