I installed gtbdk and then unzipped it.
I ran following command
tar xvzf gtdbtk_data.tar.gz
When I ran $ gtdbtk
I got error message following
ERROR The 'GTDBTK_DATA_PATH' environment variable is not defined. Please set this variable to your reference data package. https://github.com/Ecogenomics/GTDBTk#installation
Can someone help please. Thank you
