AssertionError when opening a spectral library from ENVI (.sli)

[María Angélica Prieto]

I just installed ENMAP (3.9.20211123T125541.master version / QGIS version 3.22.7-Białowieża) and I’m triying to open a .sli file from Open spectral library window. I got the following message about the python process:

2022-06-21T16:58:10     INFO    Please add / activate spectral processing algorithms

2022-06-21T16:58:17     WARNING    Error de Python : Ha ocurrido un error mientras se ejecutaba el código de Python: Vea el registro de mensajes (Error de Python) para más detalles.

Also, got this in the error traceback:

assert hdr is not None and hdr['file type'] == 'ENVI Spectral Library'
AssertionError

Which complement or package am I missing? Thank you in advance.

Please share the content of the *.hdr file associated with the ENVI speclib.

addresses #1383 - more flexible parsing of envi spectral library hdr file type. can be ".Spectral Library."

@María Angélica Prieto please check the “file type” in the hdr file of your spectral library. It need to be “file type = ENVI Spectral Library”. However, with the changes commited above, this is now handled a bit more flexibe to allow “file type = Spectral Library” as well.
