+For split package:
+
+To create an archive from the GTDB-Tk release data parts:
+
+1. Ensure all parts of the GTDB-Tk release data are in the same directory.
+2. Open a terminal or command prompt.
+3. Navigate to the directory containing the parts of the GTDB-Tk release data.
+4. Use the following command to concatenate all parts into a single archive:
+   cat gtdbtk_r220_data.tar.gz.part_* > gtdbtk_r220_data.tar.gz
+
+5. Once the command finishes executing, you will have a single archive file named 'gtdbtk_r220_data.tar.gz' in the same directory.
+
+You can find the gtdbtk_r220_data.tar.gz.part_* files under:
