Hi, You’re welcome, but I don’t have any further details than what is already given in the manual: <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/structuremeas/structuremeas.html#axes> It’s recommended you send Chimera questions to chimera-users@cgl.ucsf.edu instead of me directly, in case others may be able to provide better answers!

Hi Elaine Meng, Yes i could figure now the axes as well as angle measurements between them and thanks for your timely help.
I would be happy if you could tell me the principle on which these axes are calculated. I have noticed that it's from Eigen vector values that are calculated for the coordinates of the set of atoms.
I'm really interested on the backend for this calculation particularly, might help a bit progressing more for my research.
Thanks again.
