CMaxSize [µm] (Cells’ Maximum Size)
Range: [0, 100], Default: 70, Unit: [μm]
This parameter serves the purpose of setting the maximum cell size (diameter in micrometer) used for
considering objects for evaluation. It distinguishes large dirt particles from cells.
AggrMinSize [µm] (Aggregate Minimum Size)
Range: [8, 50], Default: 12 or 15 depending on Cell Type, Unit: [μm]
The minimum size of the region that should be analyzed as an aggregate.
BorderWidth [pixel]
Range: [0, 1000], Default: 10,Unit: [pixel]
The border frame around the image not used for evaluation.
The Borderwidth should generally not be adjusted. Consult with a Roche Service representative before
making any adjustments to this parameter.
AggrMaxSize [µm] (Aggregate Maximum Size)
Range: [10, 200], Default: 100, Unit: [μm]
The maximum size of the region that should be analyzed as an aggregate.
LCAggrApp (Live Cells’ Aggregate Appearance)
Range: [-10, 10], Default: 0, Unit: [absolute value]
This parameter influences the recognition of living cells in aggregates. The higher this value is set, the more
living cells are recognized in aggregates. The lower this value is set, the fewer living cells that are recognized in
aggregates.
DCAggrApp (Dead Cells’ Aggregate Appearance)
Range: [-10, 10], Default: 0, Unit: [absolute value]
This parameter influences the recognition of dead cells in aggregates. The higher this value is set, the more
dead cells are recognized in aggregates. The lower this value is set, the fewer dead cells that are recognized in
aggregates.
MinPollutionArea [µm] (Minimum Pollution Area)
Range: [50, 1000], Default: 100, Unit: [μm]
This parameter determines when an image will not be analyzed (i.e., the size [diameter in micrometer]), that an
object (e.g., dirt or bubbles) must have for an image to no longer be analyzed.
The use of the sliders, especially in combination, can lead to unexpected results.
