Pereadr

Purpose

Reads PerkinElmer files into a DataSet object.

Synopsis

data = pereadr(filename,options)

Description

Input is the filename of a PerkinElmer file to read. If omitted, the user is prompted for a file. The reader reads files of type:

image,

line scan,

spectrum,

intensity map,

.VIS visual image

This function is implemented using code obtained from MatlabCentral PerkinElmer IR data utility [1] submitted by Ben Perston. Multiple input files must contain the same axisscale for the wavelength (variables) mode. The imported files are returned in a Dataset Object.

Optional Inputs

• filename = specifies the file(s) to read using:

(a) a string specifying a single file to read

(b) a cell array of strings specifying multiple files to read

(c) the output of the MATLAB "dir" command specifying multiple files to read

If fname is an empty string or matrix or is not supplied, the user is prompted to identify file(s) to load.

• options = an optional options structure. See Options below.

Outputs

• data = a DataSet object containing the spectrum or spectra from the file(s), or an empty array if no data could be read. If the input file(s) contain any peaktables these are extracted and returned in the output DataSet object's userdata field.
• wrn = a cell array of warnings issued during the reading of the file.

Options

Input 'options' is an options structure containing the following fields

• filetype: [{'fsm'}| 'imp' | 'lsc' | 'sp' | 'vis'] Specify the type of the data in the imported file(s).
• waitbar: [ 'off' |{'on'}] Governs display of a progress bar when doing multiple file reading.
