Filaments are common yet mysterious structures in dense clouds. Their nature and importance awaits to be explored. Are they the main device to transport mass or merely byproducts of turbulence? Most arrays before ALMA cannot reliably deliver kinematics to answer fundamental questions about filaments. The game has now changed by ALMA. One of the unique capability of ALMA is to truthfully image all spatial scales. This project will first investigate the imaging procedure of available methods and apply to ALMA data on large-scale structures, including our own projects.
