Dear programmers -
Phil Evans writes in acta D57 1355 (2001) on p 1358 section 5.2:
"....the convention used in AMoRe (Navaza, 1994)
and other CCP4 programs (Collaborative Computational
Project, Number 4, 1994) is to rotate by gamma around z, then by beta
around the new y, then by alpha around the new z again,
R = Rz(al)Ry(be)Rz(ga)"
This seems correct, as the first rotation is applied first to
vector x, then the second to the new one, etc, thus
x' = (Rz(al)(Ry(be)(Rz(ga)x)))
In J.Appl.Cryst. 30 402-410 (1977) in the convrot description,
Sascha Uzhumtsev lists in table one for (Navaza 1994):
alpha about Z, beta about Y and gamma about new Z
and gives the *same* resulting rotation
Rz(al)Ry(be)Rz(ga)
This seems to be a contradiction I cannot resolve?
Thx, br
