The Database Options are listed by database name, and are organized in a tree-like structure. When a database is chosen from the displayed list, the available categories of options are displayed.
Available options vary from database to database.
Database Options are options that only apply to a specific database. The Database Options fall into four broad categories, each with more specific subcategories. The Tree Options are software configurations which affect the display of MeSH Trees. The branches of the MeSH trees may be set to display with variable levels of indentation. You may set the level of indentation to any whole number of spaces between 1 and 20.
