Errors of BIOMASS L1B product_DGM.export_abs_bands_separately function

[sht9010]

Dear Clement Albinet and giopalumbo,

When I process the L1B product with BiomassProduct.py, and export the data to tiff files, by using:

import BiomassProduct
from pathlib import Path

###Define the path to the STA product
test_dgm_path = r"G:\BIOMASS_DATASET_L1B\BIO_S2_DGM__1S_20251212T134812_20251212T134833_T_G01_M01_C01_T009_F118_01_DJJYF5"
product_DGM = BiomassProduct.BiomassProductDGM(test_dgm_path)
product_DGM.export_abs_bands_separately(r"C:\Users\Dell\Desktop\export_abs_bands_separately")

I got 4 files,

"C:\Users\Dell\Desktop\export_abs_bands_separately\band_4.tif"
"C:\Users\Dell\Desktop\export_abs_bands_separately\band_1.tif"
"C:\Users\Dell\Desktop\export_abs_bands_separately\band_2.tif"
"C:\Users\Dell\Desktop\export_abs_bands_separately\band_3.tif"

However, these datasets have no geotransform information, and reported,

✔️ Complex polarizations loaded: HH, HV, VH, VV.
🗺 CRS: None, GCPs: 35 trovati.
C:\Users\Dell.conda\envs\biomass_env\lib\site-packages\rasterio_init_.py:366: NotGeoreferencedWarning: The given matrix is equal to Affine.identity or its flipped counterpart. GDAL may ignore this matrix and save no geotransform without raising an error. This behavior is somewhat driver-specific.
dataset = writer(

Also, the output image locations were shifted from the google earth image,

Could you please help us to solve this problem?

Thank you very much.
