4.6.5 Customizing a Display
Showing and hiding the axes bar *
You can hide the axes bar on top of the display to save space and obtain a larger view
of your data.
Right-click anywhere in the window and deselect Display Header.
Showing and hiding the data stream names *
You can show the data stream type of each channel.
Right-click anywhere in the window and select Display Labels.
Using the crosshairs *
Right-click anywhere in the window and select Display Crosshairs to show crosshairs.
You can use the crosshairs to manually estimate peak heights and time points.
Customizing the display colors
Right-click either an axis or a trace to assign a new color to it. You can either choose one of the
basic colors or define a custom color. You can assign a different color to each data stream. This is
especially useful if you use a background picture or if you like to assign specific colors to specific
kind of data.
(* = Available only for Data Display)
4.6.6 Displaying a Background Picture
You can load a photo of your preparation as a background picture to see which signals belong
to which region of the preparation. This feature is only intended for MEAs with the standard
8x8 electrode grid. The file path is saved together with the data file when you record data after
loading the picture. You can unload a picture again with the command Unload Image.
If you are using a MEA120System, you can load two images, one for each MEA (A and B).
If you are using an USB-ME256-System, you can load four images, one for each MEA (A, B, C
and D).
Note: File paths are absolute, that means MC_Rack cannot find picture files if they have been
moved to another folder or directory. An error message will inform you in this case.
On the File menu, click Load Image (MEA A) for MEA A or Load Image (MEA B) for MEA B,
and if available Load Image (MEA C) for MEA C, and Load Image (MEA D) for MEA D.
1. Select an appropriate image file and click Open.
2. Add a Data Display (or an Analyzer with display) to your rack. Select a MEA layout (A, B, C
or D).
3. On the display, click Show Image. You can now see the picture.
4. Now, you map the channels to the electrodes in the picture. Hold down the SHIFT key,
point to any electrode, for example, the top left, and double-click. A text box opens.
5. Type in the number of the electrode according to the MEA layout, for example 21.
6. Hold down the CTRL key, point to any electrode in another row, for example the bottom right,
and double-click.
