axis() command giving error in 5.11.2 (and not in 5.10.2)

What do you want to do?

compute misorientation axes

What data do you have?

I have a set of orientations (3ct in this example, but happens with larger sets as well).

I want to compute the misorientation of each orientation to the mean-orientation of the set.

What code do you use?

axis(o, mean(o))

Please provide minimalist code with code in the following form


a = axis(o, mean(o));

What result do you get I get an error (see below)

What result do you expect

I expect axes returned as with previous versions (i.e., 5.10.2)

Error Message If you get an error message copy and paste it below

Error in project2FR_ref (line 84)
q.a(changeSign) = -q.a(changeSign);

Error in quaternion/project2FundamentalRegion (line 44)
  q = project2FR_ref(q,CS1,q_ref);

Error in orientation/project2FundamentalRegion (line 17)
  ori = project2FundamentalRegion@quaternion(ori,ori.CS,varargin{:});

Error in orientation/axis (line 52)
    po2 = project2FundamentalRegion(o2, o1);

What MTEX version do you use? This is occurring in MTEX v5.11.2
