TCBG strives to make its software accessible to the biomedical community through a variety of training opportunities, workshops, classes, presentations and demonstrations. For those who cannot attend these training events, we post and maintain tutorials that scientists can work through at their own speed, as a means of learning the best use of the VMD and NAMD software packages. The page below offers tutorials on tools created by TCBG, and some tutorials from other groups. Proceeding through a tutorial requires a copy of the tutorial text (in pdf or html format), tutorial files in place on the user's computer, and installation of VMD, NAMD, and other required software as documented at the start of each tutorial. Most of the tutorials are usable on Windows, Mac, and Unix/Linux platforms. It is suggested that you use the latest machine you have available; while the tutorials will run on older machines, it may be slow going.
