Import Spectral Signatures directly for hyperspectral analysis

Hello,

I am new to matlab struggling with something that is possibly quite basic. I was hoping to run something similar to this tutorial: https://au.mathworks.com/help/images/classify-hyperspectral-image-using-sam-metric.html using spectral signatures from a different library called Ecosis. I was wondering if there is a way to manually import these signatures?

Presently Image Processing Toolbox Hyperspectral Imaging Library supports reading data from ECOSTRESS spectral library. You can use readEcostressSig function to read spectrum by specifying filename (.txt files).

Do you have specific format for EcoSIS spectral library?
