SweepFormula: P/x subtraction

• Split into two issues: One for DAQ and one for display
• Think about doing it in the wavebuilder (check with experts and other software)

Implement p / x subtraction in MIES.

This is a technique used to subtract leak (aka linear) currents from current traces.

Desired workflow:

• User builds stimset in waveBuilder e.g. vClamp1
• At data acquisition, if user has activated p/x (user defines x; -4 is common), the stimulus set is modified by MIES and then acquired.
• In the first sweep, MIES acquires the waveBuilder vClamp1 sweep 1. In the same sweep, immediately following vClamp1, vClamp1 / x is acquired. vClamp1 / x is repeated x times.

So, a stimset that looks like this:

Get acquired like this when x = -4:

• When p/4 data is acquired, provide the user with the option of displaying the subtracted traces. The display of subtracted traces could be done using SF.

• Subtraction formula: vClamp1 - (x * (average of vclamp / x traces)).

The issue names waveBuilder, DAQ, display, and SF as the areas to investigate; begin by resolving the requested split between acquisition and display and checking how waveBuilder should participate. Confirm the workflow with project experts, then define completion around acquiring the paired p/x sweeps and offering the specified subtraction display.
