1. Click User Defined Map.
2. Set up a MEA layout with a 5 x 5 grid using Rows and Columns. The MEA layout appears
on the right side of the dialog box and in the data display.
3. Click into the empty squares of the electrode grid and select the desired channel numbers
from the Channel drop down menu. The data display shows the channels in the selected
layout accordingly.
4. The electrode referring to channel No.13 (in the middle of the first row) is bigger than the other
electrodes. Click 13 in the electrode grid. Enlarge the electrode in the data display with X-Extend
= 300 and Y-Extend = 200 by overwriting the 0 in the numeric updown box or clicking the arrow
buttons.
5. To change the position of the electrode in the data display use X-Offset for moving it to the
left (negative integer) and to the right (positive integer), and Y-Offset for moving it downward
(positive integer) and upward (negative integer). The X- and Y-Offset has a range from -100 to
+100. Overwrite the 0 in the numeric updown box or click the arrow buttons. The layout displayed
on the data display is updated immediately.
6. The electrode referring to channel No. 23 is bigger as well. Do the same procedure to enlarge
and move it as described in point 4 and 5. Repeat this procedure as often as necessary, and you
are able to build your custom display layout.
If you have two amplifiers in your setup (MEA120 System), use Channel Offset to assign the
custom layout to the correct data stream. Please read also next chapter Selecting data streams.
Until today, it only makes sense to give 0 in Channel Offset for connecting the custom layout
to Electrode Raw Data 1 or 64 for connecting the custom layout to Electrode Raw Data 2.
If you want to keep the custom layout for later use, click Save and enter a file name.
