Well Plates

Well Plates > Define Plate

This task specifies shape and size of a well plate as well as the working area of single wells.

Select a wellplate type you use from the database or define a custom wellplate. The wellplate definition includes dimensions, number of wells and placement of wells.

Requires:
Device: 

Motorized Stage

Well Plate name

Type the name of your well plate.

Select from DB...

This button opens the well plate database, where you can find many standardised well plates.

Note

Type your well code into the Search field to find your well faster.

Custom Well Plate...

This function opens the Define custom well plate window where it is possible to adjust all key parameters of nonstandard well plates. Please see Custom Well Plate Options.

Align Well Plate...

Opens the Align Well Plate dialog window. Please see Well Plates > Align Well Plate Holder.

Note

Well plate alignment can be done inside the job definition using the Well Plates > Align Well Plate Holder and is job dependent - has to be repeated with each new job. It is also possible to align the plate globally by HCA/JOBS > Well Plate > Align Well Plate Holder. This alignment is saved into the database and applied on new wellplates automatically.

Custom Well Plate Options

Plate name

Type the name of your well plate.

Rows

Type how many rows does your well plate have.

Columns

Type how many columns does your well plate have.

Well shape

Select which shape does your well plate have. Circular, Rectangular and Rounded Rectangular are available.

Well names

Here you can choose the single well labeling method. The Per axis method enables labeling the wells with letters and numbers, applicable on both axis. The Per well method labels the wells from number one, from the left side to the right side and from top to bottom. Specify your choice in the Column and Row combo box.

Plate length, Plate width

Define size of the wellplate.

Column spacing, Row spacing

Define distances between adjacent well rows.

Row offset, Column offset

Define distances from the edge of your plate to the center of the A1 well.

Well diameter

Define the diameter of a single circular well.

Well height, Well width

In case of rectangular well shape, define its height and width.

Corner Radius

If you are using a Rounded Rectangular well shape, here you can set the corner radius in [mm].

Column, Row

In Per axis mode this function assigns either letters or numbers to all columns and rows. You can set the numbers and letters Order to be Ascending or Descending.

Well Plates > Use Autodetected Plate

This task selects the globally stored auto-aligned well plate as the well plate to be used inside a particular job.

Well Plates > Align Well Plate Holder

This function determines the exact position of a well plate on the XY stage. Typically, this task is executed during runtime.

Before a wellplate is scanned, it must be aligned properly, so that the coordinates of wells are not misplaced. Select wellplate orientation and find the A1 well.

Correct Wellplate Alignment - Well Calibration 
For a precise alignment, at least two wells should be calibrated. Each well is calibrated using one or more points based on its shape and selected calibration method. To align your wellplate correctly follow this procedure:

  1. Select a calibrating Method from the combo box (defines how many points have to be added for each well).

  2. Choose a well in the wellplate preview and click on in (Recommended Wells are colored in gray).

  3. Display live image from the camera. A cross will be displayed in the image.

  4. Move the XY stage so that the edge/center/corner (based on the chosen method) of the well is in the center of the cross.

  5. Click Add.

  6. Now use the stage to add more edge points on the same well (add as many points as you selected in the Method combo box; e.g. for Center Point one is sufficient). If all calibration points of a single well were correctly added, the well is highlighted green.

  7. Choose a second well in the wellplate preview and click on it.

  8. Add calibration points for this well (repeat procedure from step 3).

  9. If done properly, two wells are calibrated (highlighted green) and the well plate is correctly aligned. To increase accuracy of the alignment, calibrate more than two wells.

Note

The more wells you calibrate, the more well plate alignment imperfections are eliminated. Two calibrated wells can rectify the XY position and rotation of the well plate. Three calibrated wells can rectify the XY position and a slight tilt of the well plate. Four calibrated wells can rectify the XY position and a large tilt.

However one well is also enough for rough calibration. If one well is used for calibration it is assumed that the whole well plate is placed orthogonally on the stage with its top-left well oriented to the top-left stage corner.

Align Wells tab

Name

Type the name of your align.

Align

Choose a well plate defined by the Well Plates > Define Plate which will be aligned.

Method

Specify the calibration method based on the number and position of the calibration points on the currently calibrated well.

Add

Adds point coordinates into the well alignment table.

Remove

Removes the selected XY coordinate.

Remove All

Removes all points from the alignment table.

Test Well

Select a calibrated well and click this button to move to its edge. This way you can check the correct edge calibration.

Test tab 
This tab is useful for checking the correct alignment of the whole well plate. Hover the cursor over any well. Available test move locations are displayed. Click on a gray circle to move the stage to this exact position and verify the alignment precision.

Well Plates > Detect Plate Automatically

Automatically detects and aligns the well plate on the stage. AI driven algorithm is used for the detections. The result is stored globally - one auto-aligned wellplate can be used by any other job or by Wellplate Navigation. Advantage of this task is that it is not necessary to align the plate holder on the stage or to know/define an exact plate type. It can be be directly used by the Well Plates > Select Wells task as plate definition.

Requires:
Device: 

Motorized Stage, 4x objective

Well Plates > Select Wells

Specifies which wells of the selected well plate are actually used in the experiment.

Use the A1 well for alignment and leave the outer perimeter of wells unused.

Requires:
Device: 

Motorized Stage

Before selecting any wells you need to define the well plate by the Well Plates > Define Plate task. After the plate definition, you can select the wells using the Select Wells task. The wells can be easily selected by clicking and dragging over the well board. If you hold down the shift key, you can select remote parts of the well plate. If you hold down the control key and drag over wells already selected, you exclude them from your actual selection. You can also select single rows / columns by clicking on their letter / number. If using mouse for the well selection, the selected values automatically appear in the Select rows or Select columns fields where you can manually rewrite them using comma (for separating the values) and dash (for entering range values).

Name of the Selection

Type the name of your well selection.

On Well Plate

Here you can switch between different well plates created in your actual job.

Selection color

Choose any color you wish. This color is then going to be used to visualize the wells selected.

Well Ordering

This function defines the order in which the wells are passed (e.g. during a Loop). Meander (the most effective way of moving between wells), Left to Right and Top to Bottom options are available.

Select all

Selects all wells from a chosen well plate.

Select Rows

Enter a single row or a range of rows that you want to select.

Select Columns

Enter a single column or a range of columns that you want to select.

Requires:
Selection
Full

Adds all wells to the selection.

Empty

Removes all wells from the selection.

Selection Color

Resulting color of the selection.

Well Ordering

The movement direction used when going over the selection in a loop.

Use it inside Well Plates > Loop over Wells and Conditions > Condition (If) to modify a well selection.

Requires:
Well Plates > Edit Well Selection

This task enables the user to manually adjust the automatically generated well selection at run time.

The user can modify the selection of wells right after automatic Cells Detection.ai is performed.

Requires:
Well Plates > Use Well Selection from Sample Navigation

This task loads the selection of wells currently defined in the View > Acquisition Controls > Sample Navigation window.

Requires:
Well Plates > Create Well Selection from Point Set

This task uses a point set to create a new well selection.

Requires:
Well Selection on

Choose a well plate definition.

containing

Specify the point set.

Well Plates > Loop over Wells

Runs the contained tasks on each well of the selected well selection.

Used for wellplate analysis. The wells are either analysed one-by-one (fast timelapse experiments) or in multiple well-loops (e.g. 1: pre-focus all wells, 2: capture each well).

Requires:
Device: 

Motorized Stage

Loop

Type the name of your loop.

over

Switch between different well selections available within your job.

Split storage per well

This option influences how the system stores the captured data on the disk. If checked, separate ND2 file will be created for each well.

Use Wells with ... Label

If your wells are labeled (by the Well Plates > Label Wells task), you can loop only over wells marked with the selected label.

Advanced

If you select this option, the Loop over wells will be performed only on wells with defined class typed in the Loop over wells in class field. The class number can be assigned to each well using an expression. The Class can be defined in the System > Expression task - find a parameter named Class under Job / Name of your Well Loop / CurrentWell / Class. Insert this expression by double-clicking on it and use given operators to define your class (e.g.: Job.WellLoop.CurrentWell.Class=2). In our case 2 is the Class we fill into the Loop over wells in class field.

Note

Loop over Wells does not move between the wells on a well plate by itself. It is therefore impossible to expect pictures of single wells by placing just Capture inside the Loop over Wells. To do so, you have to place the Move to Well Center task (Well Plates > Move to Well Center) inside the loop right before capture. This task tells the loop to move to the appropriate well.

Well Plates > Label Wells

Enables the user to label, add a description or metadata to each well or a group of wells.

Label positive, negative and control wells and add the quantity of the solution used so that the analysis results can be sorted based on the given label.
