Material Studio - selective molecule movement

So, working with Material Studio is awesome. You get to handle bigger, complicated and even unimaginable system. But I am facing problems in very minute functioning. I recently faced two problems, but managed to resolve on my own. Somehow, tutorials doesn't help in resolving them and you end up doing some exercise on your own to get the solution.
Among these, the problem of bringing two molecular structures in one window and then adjusting one molecule by moving it around, while other structure remains untouched, as it is. Actually, this should not be a problem to do. There is a simple way of doing this. Select the molecule to be moved and then there is a symbol (button) to select, which allows you to selectively move that molecule only. This is the same way it can be done in Material studio too. 
But among all the dozens of symbols, the new person handling MS, kind of gets lost. So, what he does is check the tutorials, for any help. But the tutorials don't talk about such menial job. Atleast I couldn't find it. Then you start checking on other platforms like researchgate or what not for the solution. Apparently, all MS users are experts right from the beginning. They don't face such issue probably.
I faced it, I struggled with it and then after clicking almost every symbol on MS ribbon, I finally succeeded in getting the solution. So, just in case you are also struggling with MS working on this problem, you can find here the button symbol encircled to be clicked . It silently resides in the group of buttons allowing you to move molecules around. But you don't feel its existence, until you need to use one.

AutoDock Vina protocol: For Molecular Docking

There are many softwares available for carrying out molecular docking calculations. Many of these softwares are paid, while some of them are free. AutoDock is one such freely available software. Earlier, there was AutoDock 4.0 version available. One of the problem with the software was the space it would occupy, if you attempt to do multi docking. Recently, there is another algorithm made available under autodock. It is called AutoDock Vina. This is more efficient, robust and fast algorithm. There are many tutorials available to learn AutoDock Vina including: http://autodock.scripps.edu/faqs-help/tutorial/using-autodock-4-with-autodocktools/2012_ADTtut.pdf and also a video tutorial http://vina.scripps.edu/tutorial.html    But for some reason, few changes or explanation in little detail is always required to make it understandable for a beginner to follow.  Here is a protocol designed in our group, which our Master's student follow to get acquainted to Molecular Docking s

xleap to generate prmtop and inpcrd files

Now that we have the lib file with the information for all the molecules we need to include and also the corresponding combined pdb file, creating prmtop and inpcrd files should not be a difficult task. So, to begin with we have a lib file name: molecule.lib a pdb file for 4 molecules name: four.pdb The  task is to generate a prmtop and inpcrd file. Initiate xleap using: $AMBERHOME/exe/xleap -s -f $AMBERHOME/dat/leap/cmd/leaprc.ff99 In xleap window > source leaprc.gaff # load the lib file by: > loadoff molecule.lib I am not sure but some times it helps to also load the frcmod files we created for the four molecules the information of which is stored in the lib file. > loadamberparams aldehyde.frcmod # Load the pdb file: > P=loadpdb four.pdb You should see some thing like this in the xleap window now: ------------------- > P=loadpdb four.pdb Loading PDB file: ./four.pdb Warning: name change in pdb file residue 1 ;  this residue is split i
