You can access the "Make selection" dialog box (Fig. 3.4.1) by clicking the Table>Select genes by query command on the main menu. Using this dialog box, you can select genes from the working table by search expression.
3.4.1.1. Search expression bar is a text field located at the top of the dialog box. To clear the contents of this text field, click the "Clear Expr." button.
3.4.1.2. Status bar (comments) is located below the search expression field. This field contains additional information.
3.4.1.3. The "Field" pane - the field index input bar contains a drop-down list of fields (Fig. 3.4.2.A). Click the "Select" button to view the list. The fields are presented in the following format:
Fn NAME, where n is the number of the field and NAME is its name.
If any field is selected, the status field displays the following information about the field:
$Fn: type=FIELDTYPE. Is item of group(s):x, where n is the field number, FIELDTYPE is the name of the data type for this field, and if the field you are searching for is included into other groups, then õ lists the numbers of these groups.
The "Insert" button adds the current value of $Fn to the expression (n is the field number).
3.4.1.4. Text field selection bar contains:

3.4.1.5. The "Group" pane - Group number input bar contains the following elements:
Gn NAME, where n is the group number and NAME is the group name. When the field is selected, the status bar (3.4.1.2.) shows the following information:
$Gn: type=FIELDTYPE, fields[x]: y1,y2,y3.....
where n is the group number, FIELDTYPE is the name of the data type for this group, õ is the number of fields included into the group, and ó1,ó2... are the numbers of fields included into the group.
If additional conditions are defined, they are added to the expression:
$Gn:50%

When the search is complete, an additional item appears in the "Select Table" dialog box (Fig. 3.4.4). The name of this item corresponds to the selected set of genes. You can save all gene selections obtained when working with the program and switch between them. To delete the list of current tables, click the Table>Remove all generated selections command on the main menu. Figure 3.4.4 shows a table of genes selected under the search conditions illustrated in Fig. 3.4.1.
