Compression scheme not supported when creating a Tiff object

Hi, I'm working with .tif files for the first time. Geographical data, containing elevation measurements.

When I run the following code, I get an error in the first line of code, the error message stating: Error using tifflib, 'The compression scheme 50000 is currently not supported'. Why is that? I see that '50000' is not in the list of Compression Schemes contained in Tiff.Compression. Is the data file I'm using faulty in some way?

X = Tiff('example.tif','r');
Photometric_Tag = X.getTag(Tiff.TagID.Photometric);
Compression_Tag = X.getTag(Tiff.TagID.Compression);
PlanarConfiguration_Tag = X.getTag(Tiff.TagID.PlanarConfiguration);
ImageWidth_Tag = X.getTag(Tiff.TagID.ImageWidth);
ImageLength_Tag = X.getTag(Tiff.TagID.ImageLength);
y=read(X);

since my question has not elicited any responses in two weeks - can anyone let me know if my question is not clear enough?

Yes, it is possible that the file you are using has a compression scheme that is not supported by the Tiff class in MATLAB. The error message indicates that the compression scheme with value 50000 is not currently supported.

It is also possible that the file is corrupted or not in a compatible format with the Tiff class.

Possible solution is to use a different library or tool that can handle the specific compression scheme used in the file.

I find a source indicating that it might be ZStandard http://fileformats.archiveteam.org/wiki/Zstandard

Thank you both for your answers. I had not found the ZStandard information. That's very helpful.
