Asfreadr

Purpose

Reads an AIT data file.

Synopsis

x = asfreadr(filename,options)

x = asfreadr({'filename' 'filename2'},options)

Description

ASFREADR reads an AIT spectral file (ASF, AIF, and BKH extensions).

Inputs

• filename = a text string with the name of a spectral file or a cell of strings of filenames.
  • If filename is omitted or blank, the user will be prompted to select a file graphically.
  • If filename is an empty cell {}, the user will be prompted to select a folder and then one or more AIT files in the identified folder.

Outputs

• x = takes one of two forms:

1. If input is a single file, or multiple files containing data that can be combined (same number of data points, same x-axis range, same type of data), the output is a dataset object
2. If the input consists of multiple files, but the data cannot be combined, the output is a cell array with a dataset object for each input file (see the nonmatching option defined above)

Options

options = a structure array with the following fields:

• nonmatching: [ 'error' | {'cell'} ], defines action taken when the x-axes or data types of multiple spectra being read do not match. The default choice, 'cell', returns a cell array where each element is a dataset object with data from a single file. The other choice, 'error', will return an error when the files do not match.
