This chapter provides instructions on XtalView, a crystallographic software package. XtalView can be installed in a computer by sending an email to the Computational Center for Macromolecular Structures (CCMS). In a few minutes, one should get a reply email with the download instructions. Help can be reached via email by sending a message. One has to try to be as specific as one can about the problem. Any error messages should be cut and pasted directly into the email. Every XtalView application has a textpane, where various messages are sent. It effectively forms a log of each session and it can be saved if the user wishes to do so. XtalView is organized around the concept of a crystal and a project. A crystal is a file containing unit cell, space group, and noncrystallographic symmetry information about a crystal type. Usually, there will be many data sets that share this information. To supply this information to the programs, the crystal name is passed. A project is a directory and default crystal. Typically, a project uses one crystal; however, sometimes, several crystals may be used. |
