Masking permits to exclude a specific area from the processing pipe.

Masking is accessible from the menu “Edition” - “Mask”.


The data set from which the mask is to be generated can be selected.

Selecting “Piezo” permits to apply the mask according to the altitude of the piezo at the end of the indentation. Selecting “PoCIndice” apply a mask according to the indice of the point of contact on the FD-curve (gives an information on the indentation depth). Selecting “Topography” permits to apply a mask according to the zero force image. The selection of “PoCNoise” entry permits to apply a mask according to the noise measured during the point of contact detection.

“Stiffness” entry permits to apply a mask according to the stiffness measured.

Selecting “Event”, “Event length”, “Event distance” or “Event force” permits to respectively mask data according to the number of event, the protein length computed with the choosen model, the distance from which the unbinding event occurs or the force of the unbinding event.


In this case, tomography has been chosen.


The masking threshold is chosen by clicking on the data window.

A check box permits to invert the selection. Pixels selected to be masked will be displayed, and pixel selected to be displayed will be masked.

The array displayed, e.g. piezo array will show the presence and application of the mask and the same for all arrays displayed.


All results, like stiffness, or event properties, will by filtered depending on the mask you generated. To go back and disable masking, return to mask edition and click “cancel”. This will erase your mask. To keep the mask in memory and disabled, chose the mosaic display of the experiment and click on the “M” to the lower left corner. This will change the state of the mask.


The change occurs, but is not visible on the display (no refresh). You have to close and re-open the mosaic display to see the change.
