# Configure Spike Hole Filling

After acquiring an image, enable Spike Removal to see the results. If useful data is missing, enable Spike Hole Filling.

To set up the Minimum Spike Size Z:

1. Localize the shortest spike you want to remove.

2. Measure the height of the selected spike with the surrounding area.

3. Set Minimum Spike Size Z to a value smaller than the height of the spike. For best results, set Minimum Spike Size Z to 80% of the height of the shortest spike.

To set up the Maximum Spike Size X:

1. Localize the widest spike you want to remove.

2. Measure the width of the selected spike.

3. Set Maximum Spike Size X to a value bigger than the width of the spike. For best results, set Maximum Spike Size X to 120% of the width of the widest spike.

As a result, the Spike Removal and Spike Hole Filling functions remove the spikes and fill in the missing data:
