I’m using Tapenade for my organoid analysis and would now like to set up the spectral unmixing step properly. I have 4‑channel 2‑photon z‑stacks, plus single‑fluorophore controls for each channel and an autofluorescence control.
I’m unsure how to create the spectral pattern that Tapenade requires:
– what the exact format should be,
– how spectra should be extracted from the single‑stain images (mean intensity, ROI‑based, etc.),
– whether the AF control should be included as its own endmember,
– and how the intensities should be scaled or normalized.
If you could clarify the recommended way to build a valid spectral pattern file for Tapenade, that would help me integrate it into my workflow.
