All Groups Dialog
Applicability: Cranium, Synapse

The All Groups Dialog is used throughout Cranium and Synapse for the navigation and the selection of groups.

1
The attribute to display for each group. The available attributes are: 1) formula; 2) identifier; 3) synonym.
2
The list of attributes associated with each group. Note that a group may be listed more than once. For example, if you selected the synonyms attribute, then the All Groups list may contain several entries for the same group - one entry for each synonym.
3
Option indicating if the match substring contains wildcard characters.
4
The dialog will display only those group attributes containing the match substring.
5
The molecular structure of the selected group.
Example: Using wildcard characters

When the Use wildcards option is checked, Cranium and Synapse will interpret the special characters "$" and "?" to mean:

$match zero or more characters
?match any single character

For example, the substring "?C$4" matches the group named ">C4H2S {2,3}" because: 1) "?" matches ">"; 2) "C" matches "C"; 3) "$" matches an empty space; 4) "4" matches "4". Some additional examples are shown below:

PatternMatched Group
?C$4-C5H4N {2}
C$OCH3-N(CH3)-CHO
C?H?ClH3Si
PatternMatched Formula
C?H?C3H6NO*
$C$S$C2H4O2S*2
$F3C2F3*2
  1. Open a knowledge base document using either Cranium or Synapse.
  2. Using the tabs at the top of the document, change to the Groups Chapter by clicking the left mouse button on Groups tab.
  3. Select the Go To command from the Navigation menu or press the ctrl-g keyboard shortcut. The application will display the Go To Group dialog.
  4. Check the Wildcards option control.
  5. In the Match Substring control enter the value "$s2$". (Note: the matching algorithm ignores case.) The dialog displays all groups with matching names. In our example, the only matching group was CS2.
  6. Select the CS2 group and press the dialog's OK button. The application will go to the CS2 group's page.
Tip: Use a wildcard to ignore initial characters

If you are using wildcards to match a substring, remember to include an initial "$" to ignore all initial characters. Thus, the substring "CO" will match the group name "[C]-CO-[O]" when no wildcards are being used, but will not match the group when wildcards are being used. You must include an initial "$" character to ignore the initial characters, i.e., you must use the "$CO" pattern.
