Table 1. Comparisons of estimated parameters of distribution of microtubules between original 3D HeLa images and their 2D central slices.

Number of microtubules	Mean of length distribution	Collinearity (cosα)	Cell Height
23.9±19.7	43.1±23.9	1.96±2.72	21.4±13.1

The values in the second row are MAPEs of the recoveries of parameters from the 2D slices, assuming that the parameter estimates from the 3D images are correct.
