Hi Yeo, Actually, I tried the same thing to get various conformation for the protein I am dealing with. For sampling the frames (i.e. conformation ) I tried two approaches... first I have taken frames which are at equal distance on trajectory without looking for any parameter ( randomly). Second approach I tried is on the basis of RMSD value.
But none of the approach worked for me, means I didn't got good results for docking. Do you have some better way or thought for it ?
