Sequence

A sequence can contain a collection of items, in running order and is generally used to group items for counterbalancing and routing of participant groups.

Adding a construct

You can add constructs to the sequence by clicking on New item or by dragging a compatible construct from somewhere in the study tree into the sequence. When creating a new construct, you can choose to start with a blank slate or to copy an existing construct from the study.

Removing a construct

Constructs can be removed from the sequence by dragging them to somewhere else in the study tree, or by selecting the construct using the checkbox and clicking Delete in the toolbar above the sequence table. You can also select and delete multiple constructs at once.

WARNING: All sub-constructs of the selected constructs will also be removed. If you wish keep any sub-constructs, you can drag them to another part of the study tree. Alternatively, you can drag any construct to the Spare parts bin to remove it (and its sub-constructs) from the study without permanently deleting it.

Navigate to a construct

You can navigate to any of the constructs in the table by clicking on its row or by clicking on the construct in the study tree.

Reordering constructs

The order of constructs can be changed by dragging and dropping within the table in the view panel, or by dragging and dropping within the study tree.

Assigning participant groups

One or more participant groups can be assigned to a sequence by selecting them from the Participant groups list and clicking Save. Setting the number of groups in the study can be done at the root of the study tree (Figure 1).

Counterbalancing trial blocks

Block counterbalancing is available when the sequence contains more than 1 trial block. See counterbalancing trial blocks for details.
