the response can be compared to the values assigned to the user-defined variables minResponse
and maxResponse the result of which determines whether the script continues at line 297 or is
stopped and continued with the oocyte from the next well.

Example1: Negative response expected (inward current)

Condition: if (signal > minResponse || signal < maxResponse)

maxResponse = -10000

minResponse = -200

signal = -100 ==> signal > minResponse ==> next oocyte

signal = -12000 ==> signal < maxResponse ==> next oocyte

signal = -5000 ==> signal > maxResponse and signal < minResponse ==> script proceeds

Example2: Positive response expected

If the expected response is positive (outward current) operators < and > have to be exchanged.

Condition: if (signal < minResponse || signal > maxResponse)

maxResponse = 10000

minResponse = 200

signal = 100 ==> signal < minResponse ==> next oocyte

signal = 12000 ==> signal > maxResponse ==> next oocyte

signal = 5000 ==> signal < maxResponse and signal > minResponse ==> script proceeds

3.2.2 Dose-Response Protocol

After the oocyte has been tested successfully for sufficient expression and stability, the recording
protocol continues with the does-response recording part of the script. Before the dose-response
recording starts, the usual axis scaling and ROI definition commands are applied.

If the application of different agonist concentrations steps sequentially from valve a to valve a + 1
a for loop can be used.
