[Chimera-users] axes

[Hernando J Sosa]

Thanks Eric, I got it to work now.  To summarize the code to get the axis information from an atom spec string  looks like this. Please let me know if there is a better or simpler way to do it.

#-----------------------------------
import StructMeasure

atomspec = '#0:14-37.A at CA'
atoms    = chimera.selection.OSLSelection(atomspec).vertices()
xyzs     = chimera.numpyArrayFromAtoms(atoms)
myaxis   = StructMeasure.axis(xyzs)
print myaxis
#-------------------------------------

Note that I had to import StructMeasure.

Best

H.
