Dear Nikolas,
it seems that you may have a problem with the processing, as this step should not take hours.
you should have a header file associated with your image, in order to provide information on the spectral bands. It seems that the incomplete description of image metadata associated with tiff files is often the cause of difficulties to process images with biodivMapR.
I would suggest that you convert your TIFF image using the ENVI driver with gdal (using R packages such as raster, terra or stars), and that you make sure that the header file produced with this ENVI conversion includes the 'wavelength' attribute as in the following template:
https://github.com/jbferet/biodivMapR/blob/master/inst/extdata/HDR/SENTINEL_2.hdr
It is possible to use your tiff image directly if you produce a proper header file, but you need to make sure it is correctly documented. I will try to fix the issue related to tiff images in a next version.
best regards,

Dear Jean-Baptiste,
Thank you for the answer, I decided to download the data again, now in ENVI format and everything ran smoothly.
Thanks for the help and kind regards,
