 The {dargs:argument}`"n_sample"<task_group[lmp-md]/n_sample>` tells the number of confgiruations randomly sampled from the set picked by {dargs:argument}`"conf_idx"<task_group[lmp-md]/conf_idx>` from {dargs:argument}`"configurations"<explore[lmp]/configurations>` for each exploration task. All configurations has the equal possibility to be sampled. The default value of `"n_sample"` is `null`, in this case all picked configurations are sampled. In the example, we have 3 samples for stage 0 task group 0 and 2 thermodynamic states (NVT, T=50 and 100K), then the task group has 3x2=6 NVT DPMD tasks.
 
+The {dargs:argument}`"input_extra_files"<task_group[lmp-md]/input_extra_files>` list copies each named file into every exploration task directory. The file is available there by its basename. For example, a DP-ZBL model using `use_srtab` should list its ZBL table here and reference `SiC_ZBL.txt` from the model configuration.
