I understand that the error you're encountering seems to be related to the Tiff function, which is used internally by geotiffwrite to create a TIFF file. The error message indicates that there's a problem opening the file, which could be due to various reasons such as file permissions, an invalid file path, or issues with the TIFF library.
Check File Permissions: Ensure that MATLAB has write permissions to the directory where you're trying to save the output TIFF file. Lack of permissions can prevent the file from being created.
Validate File Path: Verify that the filename variable contains a valid file path. You may want to use an absolute path to ensure that MATLAB is not trying to write to a location that doesn't exist or is not accessible.
Check for Open Files: Ensure that the file you're trying to write is not already open in another application, as this could lock the file and prevent MATLAB from writing to it.
