Hi,

I have a symmetrical molecule (A1-A2-A3-A4). Finding RMSD of its another conformer (A1'-A2'-A3'-A4') is not a problem. Since, it is a symmetrical I am also interested to find RMSD of the conformer (A4'-A3'-A2'-A1') wrt (A1-A2-A3-A4). I donot find any clue how can I do this. Any help in this regard would be great.
