"findByOrientation" command not working for fibers on Linux Scientific (XFCE desktop environment)

[Umberto Maria Ciucani]

Dear MTEX users,
I am trying to work with MTEX on a Linux Scientific (7.3?) which, as far as I understood, is the OS of our remotely accesssible computing cluster at my university.

Everything runs fine up until, while evaluating the texture of my dataset, I encounter this error (which I never ever had before on Windows):

Error using rotation (line 125)
Type mismatch in rotation!


Error in orientation/dot_outer (line 25)
  o2 = rotation(o2);


Error in quaternion/find (line 22)
d = dot_outer(lookup,ref);


Error in EBSD/findByOrientation (line 15)
ind  = find(ebsd.orientations,q0,epsilon);


Error in EvalTexNY (line 134)
componentEBSD{i,1} = findByOrientation(ebsd_rot_rec('t'),obj,15*degree);

For the single orientation the code works fine:

O1sym = symmetrise(orientation('Euler',10^-9*degree,10^-9*degree,45*degree,cs,SS));

but it does not for fibers, defined as this:

alphaF = fibre(h110,xvector);
h110 = Miller(1,1,0,cs,'uvw');
cs=ebsd('t').CS;
CS = {...
  'notIndexed',...
  crystalSymmetry('m-3m', [3.159 3.159 3.159],  'X||a', 'Y||c*',...
  'mineral', 't', 'color', 'dark red')};

when calculating this:

componentEBSD{i,1} = findByOrientation(ebsd_rot_rec('t'),alphaF,15*degree);

on:

>> ebsd_rot_rec('t')
 
ans = EBSD (show methods, plot)
 
 Phase  Orientations   Mineral  Color  Symmetry  Crystal reference frame
     2  49921 (100%)  Tungsten             m-3m                        
 
 Properties: bands, bc, grainindex, index, x, y, grainId, mis2mean
 Scan unit : um

is it because of me or not? It always worked fine on Windows.

Best Regards,
Umberto.

Hi Umberto,

for me it is working without any problems. Could you try the most recent beta version:
