Hi, everyone,
I am a starter of NAMD. Recently, I download the latest version of NAMD and namd-tutorial-file. According to the tutorial, I get all the necessary file. But at last, when I run namd, the program only generated the ubq_ws_eq.log file. In oder to find out the questions, I used the original file ubq.pdb, ubq.psf, ubq_ws.pdb and ubq_ws.pdf from the namd-tutorial-file package and then carry out the program namd2 again. But the question still appeared. Only the log file appeared and namd2 cannot generate other file such as ubq_ws_eq.dcd, ubq_ws_eq.coor, etc. Could anybody help me?

My operation system: windows7 home premium; processor: intel core i5 CPU; Type: 64-bit operation system
The verison of NAMD: I tried two versions, NAMD_2.8b1_Win32-multicore and NAMD_2.7_Win32. They all have the same result. the version NAMD_2.8b1_Win64-MPI didn't work in my system.
