  6. To create a new pattern, click Edit choose the pattern you want: Grid or Random:
    1. For Grid, indicate the number of image you want to acquire horizontally and vertically, and the Gap (distance between 2 images).
      The offset X and Y allows you to move your pattern in the well.
    2. If you choose a Random, indicate the position number and the minimal distance between positions.
  7. Save your pattern by clicking on Add.
  8. Come back to the dimension by clicking on Switch to Tiling.

  9. Choose the channel to acquire the stack.
  10. You can apply some filters by checking the box Filter unsure position:
    • Filter Radius: filter to smooth the noise by replacing each pixel by the median of the neighbor (0= no smoothing, 1= median on 3x3 square around the pixel, 2= median on 5x5 square around the pixel, …).
    • BackgroundRoi: automatic calculation of Background and BackgroundDelta values by drawing an ROI. Background will be the mean value of the ROI and BackgroundDelta will be the double of the standard deviation.
    • Background: background mean value.
    • Background Delta: amplitude of the noise.
    • Valid pixels: percent of pixel that should be far of the background to validate the position
  11. Click on Start.
