Multispec V 4.x was written  by Dr. Faiz Rahman in collaboration with Dr. J. Gamon at VCSARS (Cal State LA).  
The software is designed to take raw (radiance) output from a number of commercial spectrometers and calculate reflectance using a reference standard (e.g. Spectralon).  
The user has the option of calculating interpolated reflectance at a user-defined wavelength interval (e.g. each nm), facilitating the calculation of narrow-band reflectance indices.  
Multispec V. 4.x requires that the user calculate indices off-line (e.g. in a spreadsheet), 
whereas 5.x incorporates the ability to calculate indices.  Additionally, both versions of the software allow the user to recalculate wavelengths based on user-defined wavelength calibrations.


Notes: This file applies to version 5.1.5 built on 2-21-03 by S. Houston
MultiSpec written by Dr. Faiz Rahman 
Multispec will still function normally!

New Feature implemented in V 5.x not present in V. 4.x, applies to UniSpec DC data:
-> Reference files can be viewed and applied to produce corrected reflectance.
-> Indices and derivative spectra can be output now.
How to use this version:

1- If you want to apply reference files, click the "Select Reference files" button above the file list box.

2- You will be then greeted with a window that allows you to select files similar to the main window.  Select whichever reference files you want to examine.

3- The files that you click on will appear in the upper most box.  Click the checkboxes next to those files you want plotted.

4- Click the plot button.  This will display the reference files.

5 - You can zoom by dragging the mouse over the area you want to magnify.

To Process indices or output derivative spectra

1- Click "process indices" on the main window

2- Select the reflectance files you wish to work on

3- Select the output mode either Indices, Derivcative spectra or both

4- Select the Indices you wish to calculate

5- Click on OK,

6- Click "Calculate"

7- You will then be prompted for filenames!

*****To change Index formulas:

Open up the "INDEX" file in a text editor such as notepad, not WORD!
Follow the format!
