MassAlignment

This logic shifts image data according to its center of mass. This is required to optimize the images in case the particles are off-centered.

The optimal Pixel threshold value depends on the noisiness of the data: for good images it can be kept at 0 level. The optimal values for Circular mask fraction are 0.8-0.9. This logic only requires one input: a stack of images, which are output after mass centering.

Parameters Description
Pixel threshold Pixels lower than this value are not used for alignment
Circular mask fraction Sets the fraction of the circular mask used during normalization
