Below you will find links to tutorials about the spectragui, the main program for MVA of spectra in the NB toolbox.
I have taken a lot of time creating step by step tutorials on how to use each function within the spectragui.
You must go through all tutorials in order to use the spectra gui properly.
The tutorials are available as pdf downloads. Each tutorials will take you step by step
through how to use the functions of the gui.
NOTE: Please remove all '-' and '+' signs from any peak labels and filenames you include in your exported peak area tables. If you leave the symbols in the import script will fail and you will not be able to read your data into the spectragui. I am working on a fix for this. In general it is best if you avoid using symbols in any variable or label name when using Matlab.
