Prior Austenite Grain Reconstruction

[saurabhp92]

Dear all,
I am trying to reconstruct PAG for my martensite EBSD data. The code ran successfully for many cases but showing following error for one case.

Error using convhull
Error computing the convex hull. Not enough unique points specified.

Error in spatialDecomposition>calcBoundary (line 96)
k = convhull(x,y);

Error in spatialDecomposition (line 26)
dummyCoordinates = calcBoundary(X,unitCell,varargin{:});

Error in EBSD/calcGrains (line 26)
[V,F,I_FD] = spatialDecomposition([ebsd.prop.x(:), ebsd.prop.y(:)],ebsd.unitCell,varargin{:});

Error in PAG_MTEX (line 36)
[grains,ebsd.grainId] = calcGrains(ebsd('Ferrite'),'angle',3*degree);

Here is the first Block of my code

%% Specify File Names

% path to files
pname = 'C:\Users\Saurabh\Desktop\EBSD\Experiment\Attempt_2\5kA\Initial_5kA\PAG';

% which files to be imported
fname = [pname '\cropped.ang'];

%% Import the Data

% create an EBSD variable containing the data
ebsd = EBSD.load(fname,CS,'interface','ang',...
'convertEuler2SpatialReferenceFrame');

[grains,ebsd.grainId] = calcGrains(ebsd('indexed'),'angle',3*degree); Showing error for this line

Please help with this issue

Thanks and Regards
Saurabh Pawar

Hi,
what is the output of ebsd , repsectively ebsd('Ferrite')?
Cheers,
