the orientations a text table holds, and the other columns it names

Syntax

ori, S = loadOrientation('ori.txt', cs)

The columns named in the header.

ori, S = loadOrientation('ori.txt', cs, columnNames=['phi1', 'Phi', 'phi2', 'weight'])

The names given.

ori, S = loadOrientation('ori.txt', cs, columnNames=['phi1', 'Phi', 'phi2'], columns=[3, 1, 6])

Where they sit.

ori, S = loadOrientation('ori.txt', cs, columnNames=['Quat real', 'Quat i', 'Quat j', 'Quat k'])

Quaternions.

Description

The columns are named by columnNames or by the last header line; three of them have to be Euler angles, phi1, Phi, phi2 or Euler 1, Euler 2, Euler 3 (Bunge) or alpha, beta, gamma (Matthies), or the four quaternion components. The other named columns come back in the dictionary S, under their names without blanks. A .csv file is separated by commas.

Input

`fname`	the name of the file
`CS`	crystalFrame, by default the triclinic one
`SS`	specimenFrame, by default the default specimen frame

Keywords

keyword	default	description
`columnNames`	`None`	the names of the columns, instead of the header line
`columns`	`None`	the zero based columns the names refer to
`radians`	`False`	the Euler angles are in radians instead of degree
`delimiter`	`None`	the separator of the columns, by default blank space
`header`	`None`	the number of header lines, by default the lines before the first row of numbers
`passive`	`False`	the angles describe the passive rotation, which is inverted

Output

`ori`	orientation
`S`	dict of the other columns, one array each
