Spgreadr

Purpose

Reads Thermo Fisher SPG files.

Synopsis

out = spareadr

out = spareadr('filename')

out = spareadr({'filename' 'filename2'})

Description

Read SPG files into a dataset.

Inputs

• file = a text string with the name of an SPG file or a cell of strings of SPG filenames. If (filename) is omitted or an empty cell or array, the user will be prompted to select a folder and then one or more files in the identified folder. If (filename) is a blank string , the user will be prompted to select a single file.

Outputs

• out = 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 containing data that cannot simply be combined (different number of data points, differing x-axis ranges, etc), the output is either:

a) a cell array with a dataset object for each input file if the 'nonmatching' option has value 'cell', or

b) a dataset object containing the input data combined using the MATCHVARS function if the 'nonmatching' option has value 'matchvars'.

Options

options = a structure array with the following fields:

• multiselect = [ {'on'} |'off'] governs whether file selection dialog should allow multiple files to be selected and imported. Setting to 'off' will restrict user to importing only one file at a time.
• nonmatching : [ 'error' |{'matchvars'} 'cell'] governs behavior when multiple files are being read which cannot be combined due to mismatched types, sizes, etc.
• spectrumindex : [{1}] specifies the index of the spectrum to be imported
