Tile-class: Tile

In uFTIR: Process and Analyze Agilent Cary 620 FTIR Microscope Images

Description

Class to hold the reading of a single tile. It can also store a single tile of a mosaic, to which we will refer to as chunks. It is an extended class for SpectralInfo, adding an extra slot to hold the uFTIR Microscope readings -called Spectra. The functions tile_read and mosaic_chunk return an object of this class. The class has a defined method to plot, which can be called either by the generic plot or by plot_tile. You can use an object of this class in the following functions:

plot_tile

To plot a heat map of the reading. Available too through the generic plot.

tile_base_corr

A preprocessing function that replace negative values with zeros.

wavealign

A resampling method that allows to match the wavenumbers of a given tile/chunk with the wavenumbers of a SpectralReference.

tile_sam

When a Tile object is linked to a SpectralReference by a former call to wavealign, this function performs a spectral angle mapper match between the Tile and the SpectralReference.

get_profile_tile

To get the pixels spectra that matched a given polymer/cluster.

Value

An S4 object of class "Tile".

Slots

Spectra

array. The aquired spectra (.dat or dmd file)
