Resampling

The resampling process step recreates slices with an uniform distribution (= with a constant step size along the z-axis), using linear interpolations between slices. For this, the actual position of the slices have to be known (for instance measured during the acquisition).

[resampling]
policy = "slice_{slice_nb}_z={z_coord}um.tif"
dz = 0.01

policy refers to the format of file names including the number of the slice (slice_nb) and its z coordinates (z_coord).

dz corresponds to the step size along the z-axis to be considered in the resampling.

Plotting

The special plotting related to the resampling process step generates images in the dedicated outputs folder that are named z_positions.png and z_increments.png.

_images/resampling_positions.png — **z_positions.png** shows the slices positions before (in) and after (**out**) the resampling.

_images/resampling_increments.png — **z_increments.png** shows the slices z-increments before (in) and after (**out**) the resampling.
