Two sample files (CustomSample1.txt, CustomSample2.txt) in the “CustomDataSamples” folder show the data organization in a text data file. Each line in the data file should have four entries; diameter, number density and, real part and imaginary part of the refractive index. Each entry should be separated by a comma (,) or a tab. No spaces are allowed after each line. If the data is not properly arranged, an error message may appear.
