Error while calculating volume fraction of texture components

[Soupitak Pal]

Dear All, 

I am calculating volume fraction of different texture components present in an EBSD data set of Fe-Cr, ferritic alloy. I have used the following code: 

CS = crystalSymmetry('cubic');

SS = specimenSymmetry('mmm');

ebsd_corrected = ebsd(ebsd.mad<0.9)

ebsd=ebsd_corrected('Iron-alpha');

ori = orientation('Miller',[1 0 0],[0 1 1],CS,SS) % define the particular texture component

%number of all measurement points

all_points = numel(ebsd.x);

%EBSD subset with those points which orientations differ not more than 10° from

%ori

ori_EBSD = findByOrientation(ebsd,ori,10*degree);

%Volume fraction

Vol_ori_EBSD = numel(ori_EBSD.x)/all_points;

 

However, during execution it shows the following error: 

Error using orientation/dot_outer (line 22)

comparing orientations of different phase not yet supported

Error in quaternion/find (line 15)

d = dot_outer(quats,quat);

Error in EBSD/findByOrientation (line 15)

ind  = find(ebsd.orientations,q0,epsilon);

I have figured it out that the problem is in the line " ori_EBSD = findByOrientation(ebsd,ori,10*degree);", though I am not able to solve it. I am pretty new with MTEX. Any kind of help will be appreciated. 

Thanks

Hi Soupitak,

Did you find a solution to this problem? I am very interested.

Kind regards,
