Hi Kavya, How about just measuring the distance between the two monomer center of mass points of the homodimer and dividing that distance by 2 since the line between the two monomers will intersect the symmetry axis in the middle. For example for monomer chains A and B "measure center :.A ; measure center :.B ; distance #1,2”. Send this type of question to chimera-users instead of the chimera-dev list which is for developer programming questions. Tom

Hi,

Is it possible to find the distance between a point and a line in chimera? I am trying to find the distance from the center of mass of the protein to the 2 fold axis of the homodimer.

Thanks.
