PCA4CD está dando erro quando rodo e não calcula as PCA's. Este é o texto que aparece como erro:

Hi @HelderJardim thanks for reporting the error, english (or spanish) please.

That error seems that something happened in the PCA almost sure it is a data issue, could you share your raster (or small part of it)? To reproduce the error locally. (I think you closed it by error?)

[HelderJardim]

Do you want me to send the image? It is a Landsat 9 image (LC09_L2SP_218074_20241002_20241003_02_T1)

I'm almost sure that is due that one band in that stack is empty (with nodata or zeros), compute a PCA in that situation is impossible, so check your data carefully

[HelderJardim]

Sorry for my English. It's not very good. But when I calculated the mosaic histogram, all the bands appear, as shown in the figure.

Ok, then the error could be due to another reason, I don't have time to download it, could you clip it in a small area and send it to me please? The only way to understand what is happening is reproducing the error locally.
