Anonymous Alternative Groups

---

An anonymous alternative group is a cross between an element list and an alternative group. Element lists are restricted to single elements, but anonymous alternative groups can contain any structure that can be represented by text. Nicknames and generic nicknames are allowed in anonymous alternative groups. Anonymous alternative groups are shortcut notation for regular alternative groups, eliminating the need to specify a name such as "R1".

You can define your search query more concisely with the anonymous alternative group. By labeling an atom position as a list of substructures you specify that one of these substructures must match in the structure for which you are searching. Commas must separate the items in the anonymous alternative group. A space after each comma and the brackets are optional.

Examples of anonymous alternative groups follow:

To create anonymous alternative groups:

1. Open an atom label text box.

2. Type an open bracket "["followed by a list of elements, fragments, nicknames, or generic nicknames separated by commas, followed by a close bracket "]".
