If I don't have any information about the structure of my target molecule, what values i should choose for 'Maximum particle radius' and 'Characteristic particle radius'? So, I built a model from sequence using Itasser. Based on the model the large dimension is arounf 120A. Should I choose Characteristic particle radius less than Maximum particle radius (if yes, how much)? Giving some values for these parameters, I can read the number of particles selected for the image in the terminal where I launched cistem. The number of particles found varies a lot by changing those parameters. what criteria I should apply to optimize the values for those two parameters(keeping other parameters fixed)?
Thanks for your time,
