Although data were generated for seven CASA parameters for each sperm track, some of these measures were significantly correlated with each other and therefore are not independent.
(b) Only for samples with at least 25 sperm tracks; VSL and VCL are in [micro]m/sec.
Consequently, sperm tracks
were analyzed in two categories as defined by cells swimming either [less than or equal to] 100 [micro]m or > 100 [micro]m away from the surface of a freshly spawned egg or a microsphere.
Using a computer to capture the data, several hundred sperm tracks
from an individual tom can be analyzed.
