Description

loadODF_generic loads an ODF from any txt or exel files are of the following format

alpha_1 beta_1 gamma_1 weight_1
alpha_2 beta_2 gamma_2 weight_2
alpha_3 beta_3 gamma_3 weight_3

alpha_M beta_M gamma_M weight_m

The assoziation of the columns as Euler angles, phase informationl, etc. is specified by the options ColumnNames and Columns. The file can contain any number of header lines.

Syntax

cs = crystalSymmetry('432')
odf   = loadODF_generic(fname,'cs',cs,'ColumnNames',{'Euler 1' 'Euler 2' 'Euler 3' 'weight'})

Input

fname file name (text files only)

Options

`ColumnNames`	`names of the colums to be imported, mandatory are euler 1, euler 2, euler 3`
`Columns`	`postions of the columns to be imported`
`radians`	`treat input in radiand`
`delimiter`	`delimiter between numbers`
`header`	`number of header lines`
`ZXZ, BUNGE`	`[phi1 Phi phi2] Euler angle in Bunge convention (default)`
`ZYZ, ABG`	`[alpha beta gamma] Euler angle in Mathies convention`

Flags

`interp`	`determine the ODF by interpolation the weights`
`density`	`determine the ODF as the density of the orientations`

Example

fname = fullfile(mtexDataPath,'ODF','odf.txt');
odf = loadODF_generic(fname,'cs',crystalSymmetry('cubic'),'header',5,...
'ColumnNames',{'Euler 1' 'Euler 2' 'Euler 3' 'weight'},...
'Columns',[1,2,3,4])

Interpolating the ODF. This might take some time...
Warning: Maximum number of iterations reached, result may not have converged to
the optimum yet. 
 
odf = SO3FunRBF (m3̅m → y↓→x)
