Results Table Notes

The group specification remains active even when headers disappear. If you want to merge results, use another Data profile.

• Time bin refers to the time bins defined in the Results box of your Data profile. If you do not define time bins in the Data profile and select Time bin in the Layout window, the headers Start-End are added; no time bin is created. See Results per Time Bin.
• Zone refers to the zones specified in the Results box of your Data profile. If zones are not specified, analysis is done for the whole arena and the table shows In Arena. See Calculate the Results per Zone.
• The independent variables that you have defined are not shown in the table by default. To export the table with the independent variable values as an analysis factor, click the Layout button and move that variable to On Rows or On Columns depending on how your statistics program treats analysis factors.

Example: An independent variable Group with possible values Mutant and WT has been defined in the Trial List. To have the values of this independent variable displayed for each trial, click Layout, select the variable Group on the left and move it to the On Rows box.

• Missed Samples. This is the percentage of samples that EthoVision XT could not analyze. To reduce this percentage, see Factors Affecting the Occurrence of Missing Samples in Sample Rate.
• Subject Not Found. This is the percentage of the analyzed samples in which EthoVision XT could not find the subject. A lower value indicates high reliability of data. To reduce this value further, optimize the lighting conditions and adjust the Detection Settings to improve detection rate.
• If you select track segments with Nesting, there is no special header for them. However, remember that the results are calculated over the track segments defined, not the entire tracks.

Sort the Results Table

Aim

• To sort the results table based on the row headers.
• To sort the results table based on the values in a column.
• To change the order of and group the dependent variables in the results table.

Prerequisites

• You have run analysis (Analysis > Results > Statistics and Charts).

Sort the Table Rows Based on Their Headers

Example: Sort the results table based on the header Treatment, an independent variable with values Drug and Vehicle.

1. Click the Layout button and under On Rows move Treatment to the highest position in the list. See Modify the Layout of the Results Table.
2. Right-click one of the headers you want to sort, and select Sort Ascending or Sort Descending.

Note: If you sort the rows based on the headers on the second, third, etc. column, the rows are sorted only within that level, not globally. For example: to have all rows marked with Subject 1 at the top of the table, then all rows with Subject 2, etc., click the Layout button and move Subjects to the top of the list under On Rows, then sort the subject headers.

Sort the Table Rows Based on Cell Values

Example: Sort the table based on the values of Frequency of Zone Entries.

Right-click one of the cells containing the values you want to sort, and select one of the two sorting options.

Sort the Dependent Variables in the Results Table

Example: Sort the results table by the dependent variables; first Distance Moved, then Movement and then In Zone.

1. Click the Show/Hide button at the top-right corner and select Dependent Variables.
2. In the window that appears, select a dependent variable and click the Up and Down buttons to move a variable to a higher or lower position in the table.

The dependent variable at the top of the list in that window is shown in the first row or column in the result table.

Group Charts

How to Read the Group Charts

Charts are generated automatically from the results in the Group Statistics & Charts table. Charts are generated for the dependent variables Distance Moved, Velocity and In Zone (on separate tabbed pages). The horizontal axis shows the zones (In Border and In Center). Two data series (from the Result containers Control and Treated) are plotted.

Chart Tabs

Each tab refers to a dependent variable defined in the Analysis Profile. A tab may contain one or more charts, one for each Trial Statistic specified for that dependent variable.

Notes

• A chart is not created for the Trial statistics Standard Deviation, Standard Error and Variance.
• Charts in EthoVision XT have limited formatting options and are mainly meant for inspection purposes. If you want to make a chart for a publication, export the statistics table to Excel or a statistics program.
• If you delete a dependent variable and subsequently add it again to the Analysis profile, the properties of the new chart are set to default.
• Chart settings are stored for each combination of data profile and analysis profile. If you make an exact copy of a data/analysis profile, the resulting charts have default settings.
• Effect of Data Selection: Results per Time Bin. If in the Data profile you specify Results per time bin, time bins are always shown on the horizontal axis. The first value is 0:00:00 and represents the results calculated in the first time bin (for example from 0 s to one minute).
• Effect of Data Selection: Results per Zone. If in the Data profile you specify to Calculate the Results per Zone, you can show the zones on the horizontal axis or as data series. See Customize the Group Charts.
• If you specify both time bins and results per zone, time bins are displayed on the horizontal axis and zone statistics as data series.
• If you specify more than 1000 time bins in your Data profile, the group charts are not displayed.

To Export Group Charts

You can export one chart at a time. To export a chart as an image file, do one of the following:

• Right-click the chart and select Export Chart.
• Click the chart and then click the Export Chart button just above the chart.

The default file name is the same as the chart title. Four formats are available: Portable Network Graphics (*.png), JPEG file (*.jpg), Windows bitmap (*.bmp), and Graphics Interchange Format (*.gif).

To copy the chart to an external program, right-click the chart and select Copy, then paste it to the other program.
