Files "Trajectories_1.tar.gz" - "Trajectories_9.tar.gz" contain trajectory data for 900 initial geometries randomly generated from Wigner distribution. Each file contains data for 100 initial geometries. Directories pyrrol_k_100 - pyrrol_k_999 correspond to the above random geometries. They contain subdirectories tp1 and tp2. When only tp1 subdirectory is present - continuation of calculations. When both tp1 and tp2 subdirectories are present - branching at a cloning point: each of subdirectories contains one branch. Directories pyrrol_k_100 - pyrrol_k_999 can also contain subdirectories tp_rn_????, which contain data for corresponding tunneling trajectories. All trajectory data (including initial geometries) are written in files "Trajectory", which are ascii files with obvious format. 5. File "pyrol_k_2000.com" Input file for MOLPRO. This file is the same for all calculations, as a geometry is defined by a separate file.
