#!/bin/bash
# Generate validation trajectories for a single (task, subtask, obj) combo on HPC3.
# Output goes to mshab_data/gen_data_save_trajectories/{task}/{subtask}/val/{obj}/
#
# Usage: sbatch --export=TASK=set_table,SUBTASK=pick,OBJ=013_apple,MAX_TRAJ=100 scripts/gen_val_combo.sbatch
#
# Pipeline per combo:
#   1. gen_data.py with SPLIT=val, MAX_TRAJ=100   → val rollouts using val task_plan + spawn_data
#   2. add_pointcloud.py                          → pointcloud/{xyzw, rgb, mask}
#   3. add_xyzrgb.py                              → pointcloud/xyzrgb (1024 sampled pts)
