Overlay Sweeps

The OVS tab allows to overlay multiple sweeps in the same graph. The selection of the sweeps can be done by criteria like stimsets, clamp mode or similiar, using a step and offset calculation based on sweep numbers, or by selecting them from the listbox. Ignoring selected headstages of a specific sweep when overlaying is supported as well.

The following section describe the OVS settings.

Settings for overlaying sweeps

  • Enable: Toggle the overlay sweeps mode. When turned on, all selected sweeps in the lower list box are displayed. In the off state, only the sweep selected in Sweep Control will be shown.

  • Select: Select multiple sweeps based on criteria like stimulus set (DA and TTL) and clamp mode. Includes also None for unselecting all of them.

  • Offset and Step: Select every sweep number \(x\) which satisfies the condition \(x = o + n \cdot s\) where \(o\) is the Offset, \(s\) the Step and \(n >= 0\) an integer.

  • Headstage Removal: Toggle the ignoring of headstages. When an existing headstage is entered in the second column in the listbox, this headstage will not be displayed in the Databrowser. Headstages can also be selected interactively from the context menu in the Databrowser. For this hover over the trace you want to remove, right-click and select Ignore Headstage in Overlay Sweeps.

  • Non-commulative update: If you have enabled Display last sweep acquired in Sweep Control this option will remove the previous last sweep from the list of overlayed sweeps before adding the newly acquired sweep.

  • Clear on new RAC: Clear the list of overlayed sweeps when a new repeated acquisition cycle (RAC) starts.

  • Clear on new SCI: Same approach but this time based on the stimset cycle (SCI).

  • Listbox: The listbox allows to select which sweeps to overlay individually. The first colum has the sweep numbers and the second column holds the headstages for removal. The Headstages column can only be edited when Headstage Removal is checked. The headstages to be removed can be single headstages 0 to 7, list of headstages 0;2;6 or a range 0-2.
