Membrane-based Segmenter

Detects the cell body starting from the membrane marker.

Membrane-based Segmenter: Channel Ch1; Min intensity 8; Split sensitivity 29.62%; Max diameter 20 µm

Membrane-based Segmenter parameters

Parameter

Description

Channels

Sets the processing and analysis target channels.

Min intensity (membrane)

Sets an approximation of a membrane with the lowest intensity. This value is used for the initial thresholding of the image to extract the membrane and thus separate it from the background. This is a very important and guiding value, therefore it needs to be selected carefully.

Split sensitivity

Sets the sensitivity used to split touching objects.

Decreasing the Split sensitivity will fuse more objects

Increasing the Split sensitivity will split more objects.

Membrane Maximum

Sets the membrane maximum size. Drop down the list to select the feature

Max. diameter

Sets the value as the maximum diameter.
Note: You can measure the membrane maximum diameter directly from the dataset with the Measurement Black diagonal pencil icon on white background tool.

Max. area

Sets the value as the maximum area.
Note: You can measure the membrane maximum diameter directly from the dataset with the Measurement Black diagonal pencil icon on white background tool.

Max. volume

Sets the value as the maximum volume.
Note: You can measure the membrane maximum diameter directly from the dataset with the Measurement Black diagonal pencil icon on white background tool.

If you have set the parameters correctly, the preview (see Previewing the results) should look like this:
