ACQ4-Autopatch

Automated cell patching extension for ACQ4

Installation

Install the package into your environment with e.g.

pip install acq4_autopatch

or

git clone https://github.com/sensapex/acq4-autopatch.git
conda develop acq4-autopatch

Customize the following to suit your hardware and add it to the modules: section of your ACQ4 default.cfg file:

    Autopatch:
        module: 'acq4_autopatch.module.AutopatchModule'
        config:
            imagingDevice: 'Camera'
            patchDevices:
                PatchPipette1: (0, 0)  # bottom-left quad
                PatchPipette2: (50*mm, 0)  # bottom-right quad
                PatchPipette3: (0, 50*mm)  # top-left quad
                PatchPipette4: (50*mm, 50*mm)  # top-right quad
            plateCenter: (0, 0, 0)
            wellPositions: [(0, 0), (50*mm, 0), (0, 50*mm), (50*mm, 50*mm)]
            safeMove: True
            patchStates:
                cell detect:
                    maxAdvanceDistancePastTarget: 1*um
                seal:
                    autoSealTimeout: 60
                    pressureMode: 'auto'
                cell attached:
                    autoBreakInDelay: 5.0
                clean:
                    approachHeight: 3*mm
                    cleanSequence: [(-35e3, 1.0), (65e3, 1.5)] * 5
                    rinseSequence: [(-35e3, 3.0), (65e3, 15.0)]

Usage

Briefly:

  1. Make sure you have an active Storage directory in the DataManager module.
  2. Open the Camera module.
    1. The first time through, use this to move each pipette into its home, clean and rinse positions.
    2. In the main ACQ4 Manager window, save the home on each Manipulator.
    3. In the main ACQ4 Manager window, save the clean and rinse on each PatchPipette.
    4. Do any other calibration necessary.
  3. For each pipette, open a separate TaskRunner module.
    1. Enable the Clamp associated with this pipette.
    2. Configure the tasks to be performed after a cell is patched.
  4. Open the MultiPatch module. This is useful for monitoring.
  5. Open the Autopatch module.
    1. Press "Add Points" and add one in the Camera for every cell you'd like to patch. Repeat for each well.
    2. Pick your acquisition protocol.
    3. Press "Start"
  6. Monitor status in the "Pipettes" pane or in the MultiPatch window.
  7. Read through results or look at errors in the "Results" pane.
