error in calcGrains MTEX 5.2.1

[Maël Allard]

Dear all,

I was trying to run my mtex script (working in mtex 5.2) with the new version 5.2.1, but it returns me an error while attempting to calculate grains.

The way I proceeded is the following:

%% Import Data
ebsd = EBSD.load(fname,CS,'interface','ctf',...
  'convertSpatial2EulerReferenceFrame')

% filter out MAD higher than 1 degrees
ebsd_clean = ebsd(ebsd.mad<=1)

% Segmentation angle to define grains
segAngle = 10  *degree;

% Grain modelling
[grains,ebsd_clean.grainId,ebsd_clean.mis2mean] = calcGrains(ebsd_clean,'boundary','tight','angle',segAngle)

The error message is:

Undefined function or variable 'qq'.
Error in quaternion/mean (line 26)
  qm = qq;
Error in quaternion/mean (line 42)
  [qm,lambda, V] = mean(q.subSet(id),varargin{:});
Error in EBSD/calcGrains (line 71)
  mq = mean(qind,'robust');

Did something changed in "calcGrains" between 5.2 and 5.2.1 ?

Thanks in advance,

Maël Allard

Thank you for reporting this. It is a typo in quaternion/mean (line 26) the qq should be q.

I will fix this in Matlab 5.2.2.

Ralf.
