FTIR Data Colection and Processing

FTIR Data Colection and Processing. University of Aveiro.

ftir2table takes an .ASC file and converts it to a MatLab table and excel file.

filename should be a cell vector containing the file names along with the extensions.

getASCfiles function could be used as the input of this function to get the data from all ASC files in the current folder.

getASCfiles creates a cell array of all the ASC file names in the current folder. Input not required.

An example of usage could be:

clear,clc;

dados=ftir2table(getASCfiles);

offset=0;

for i=1:length(dados)

M=cell2mat(dados(i));

M(:,2)=normalize(M(:,2)); % Normalize peaks

plot(M(:,1),(M(:,2)-offset))

hold on

offset=offset+7;

end

%xline([1000 2000 3000],'--',{'Group1','Group2','Group3'},'LabelVerticalAlignment','middle','LabelHorizontalAlignment','right','HandleVisibility','off') % Group Indication Example

xlabel('$Wavenumber$ $(cm^{-1})$','Interpreter','latex')

ylabel('$\%$ $T$',"Interpreter","latex")

axis('tight')

legend(getASCfiles) % for easy labeling

set (gca,'xdir','reverse','FontSize',14,'FontName','Iwona') % Reverse x-axis direction
