Preliminary notes on steps for making a new tutorial in JTAT. Directory and File Structure: Window Title: Edit the file js4all/window_title.js to specify a short name for your tutorial. This will be the name of the window when your tutorial is displayed. The window name appears at the top of the browser window, in the browser tab showing the document, and on the tutorial's button in the Windows Taskbar. Copyright Holder and License: Edit the file js4all/license.js to specify the copyright holder, and the license you wish to apply to your tutorial. Molecule atomic coordinate files: Put all the PDB files needed by your tutorial in the directory molecules4all. Molecule PDB codes and names: Edit the file js4all/molecules.js to give the number of molecules (in the direcgtory molecules4all), their PDB codes and descriptions. This information appears at the lower right, in the "How To ..." section, beneath the contents, and beneath the view buttons in every chapter.
