[Chimera-users] Transformation matrices

[Eduardo Sanz-Garcia]

I am getting the rotation matrices (I am not interested in the 
translation column) using matrixget command.
My naive question: Should I use in this way:

x'                    x
y' = [3x3 matrix]     y
z'                    z


or in this other way?

z'                   z
y' = [3x3 matrix']   y
x'                   x


Thank you very much.
