Median and SD of the observed and expected lamin fiber to NPC center to center distances, the difference between them, P values (see Materials and methods), and number of NPCs. The data in each row were collected from 10 cells. The Mann-Whitney U test and Ansari-Bradley test were used as described in Materials and methods.

aP values above the Bonferroni corrected α value of 0.05/8 tests = 0.006.
