Each image is a raw image of a given fluorochrome.
A given fluorochrome targets a subset of chromosomes, more informations can
be found in:
*Automatic Segmentation and Classification of
Multiplex-Fluorescence In-Situ Hybridization
Chromosome Images
by
Hyo Hun Choi, B.S., M.S.
*
Choi gives an example of CCD integration times:
*
An example of integration times is [DAPI, Aqua,
Green, Gold, Red, Far Red] = [0.14, 6, 0.76, 6, 2.96, 1.4] seconds*
He also gives an example of spectral mixing in the raw images:

With the vysis data set
(example:https://github.com/jeanpat/MFISH/tree/master/MFISH_TIFF/V13__40),
a given fluorochrome corresponds to several chromosomes, in the
spectrumAqua image the chromosomes 3,10,11,13,15,20,21,22,X,Y are visibles.
A: S. Aqua
D DAPI
F: Far Red
G: S. Green
R: S. Red
Y: S. Gold
To perform "perfect" spectral unmixing, I suppose it's necessary to know
the integration time, the characteristic of the microscope bandpass
filters, the emission spectrum of each fluorochrome; but would it be
possible to make some kind of "estimated" unmixing from only the images
themselves?
Best regards
