  - `hpc_user`: Your user ID on the HPC (i.e., "bsc32xxx"). It is required if "queue_host" is not 'local'.
 - `data_dir`: The path to the data repository if the data is not shared.
 - `lib_dir`: directory on the HPC where the startR R package and other required R packages are installed, accessible from all HPC nodes. These installed packages must be compatible with the R module specified in `r_module`. This parameter is optional; only required when the libraries are not installed in the R module.
+- `run_dir`: The directory to run the startR jobs. It is useful when the self-defined function has relative path.
 - `init_commands`: The initial commands in bash script before R script runs. For example, the modules required by computation can be loaded here.
 - `r_module`: Name of the UNIX environment module to be used for R. If not specified, `module load R` will be used.
 - `CDO_module`: Name of the UNIX environment module to be used for CDO. If not specified, it is NULL and no CDO module will be loaded. Make sure to assign it if `tranform` is required in Start().
