## Required files

**Program Files** of the mat2Dcorr toolbox:

- mat2dcorr.m
- updcorrplt.m
- readme.txt

**Software**:

- Matlab R2014a or newer

## Extra files (spectral data files)

- linescandata.mat - example data file in the trace (2D) data format, see also trace data format
- IR-cerebellum-100x100.mat - example data file in the hyperspectral imaging (HSI) data format (FT-IR spectra from hamster cerebellum), see also imaging data format (Matlab)
- IR-cerebellum-50x50.mat - example data (50 x 50 spectra, interpolated), Matlab HSI data format
- MALDI-cerebellum-100x100.mat - example data file (100 x 100 spectra) in the HSI data format (MALDI-TOF mass spectra from hamster cerebellum), see also imaging data format (Matlab)
- MALDI-cerebellum-50x50.mat - example data file (50 x 50 spectra, interpolated), Matlab HSI data format
- Raman-cerebellum-100x100.mat - example data file (100 x 100 spectra) in the HSI data format (MALDI-TOF mass spectra from hamster cerebellum), see also imaging data format (Matlab)
- Raman-cerebellum-50x50.mat - example data file (50 x 50 spectra, interpolated), Matlab HSI data format
- fftsyncro.mat - result file of 2D correlation analysis by the mat2dcorr toolbox using the FFT 2D-COS option, for details of the result file format refer also to the section format of a 2D-COS result file (Matlab)
- statssyncro.mat - result file of 2D correlation analysis by the mat2dcorr toolbox using the statistical 2D-COS option, for details of the result file format refer also to the section format of a 2D-COS result file (Matlab)

## Installation

- Download files 1.-3. + some test data (see above) and and copy them into one single directory, for example into a directory
*mat2dcos*. - Add then this directory to Matlab's search path. For this start Matlab and type

>> addpath('Mat2DcorrPath')

at the Matlab command prompt, where *Mat2DcorrPath* denotes the full path where the the toolbox resides (i.e. *mat2dcos*).

Example of Mat2DcorrPath: *C:\Users\Tim\Documents\Matlab\Mat2D*

- To start mat2Dcorr type

>> mat2dcorr

at the Matlab prompt.

This will open two different windows:

- A window entitled '2D correlation analysis ... ' which shows the 2D correlation spectrum and mean spectra obtained from the x- and y-spectral data
- The 2D-COS control window (see screenshot below)
