Dear LW,
Chimera does not do docking calculations.   It is often used to view the results (output) from  docking programs.   You might try asking on a more general molecular-modeling forum such as ccl.net  about which docking program(s) might be good for your situation.

In Chimera, you could try positioning the structures manually by freezing one in place and moving the other with the mouse, but it can be difficult, and you would have to judge the result simply by eye.  For more details about how to move one structure at a time with the mouse, see:

I hope this helps,
Elaine

I also have a PDB file(as attached )built to model SDS micelle surrounded by water. Does Chimera allow people to dock these two molecules and generate a combined PDB file for further analysis? While the structure of Saposin C in the presence of SDS micelle, NMR data indicate that the open hydrophobic core is in contact with SDS micelle. Is it possible to use Chimera to determine the relative orientation of the two molecules where (i), they are in intimate contact, (ii), there is no clash, (iii), the shape complementarity is at its optimal?
