Can't use zero range method

[Emanuel Benatti]

Hi everybody

I'm working with a CuAlNi alloy with really sharp texture, so I've wanting to use the zero range method. However when I put the zero range option as an input for the calcODF routine I get the following:

CAN_odf = calcODF(CAN_corr, 'zero_range', 'halfwidth', 3*degree, 'b');

------ MTEX -- PDF to ODF inversion ------------------

applying zero range method to (111)........................ - reduction: 2663 / 4958

applying zero range method to (220)........................ - reduction: 23 / 4958

applying zero range method to (400).Error using PoleFigure/zeroRange (line 66)

Zero range methods has canceled out all orientations. Chose better parameters

Error in PoleFigure/calcODF (line 77)

if check_option(varargin,{'ZR','zero_range'}), S3G =

zeroRange(pf,S3G,varargin{:});end

I understand that, probably because the sharp texture, I need to tune the parameters in order to not to get all orientations cancelled out, but I've tried with different resolution and half-width values and I'm still get the same message. If I don't use the zero range method I'm getting some spurious texture components that shouldn't be there. They can be seen specially in the center of the (111) PF. I'm using MTEX 4.3.1. I also attach the data and the scripts used for the import and the defocusing and background correction.

Thanks in advance.
