System Requirements

FAST is optimised to run on Microsoft Windows 10, Mac OS X El Capitan or later, and Linux x64 systems.

Imaging Requirements

FAST has been designed for use with negative phase contrast microscopy. Other imaging modalities, with bright cells on a dark background, have not been tested but may work.

FAST is not designed to analyse raw semen, it is specifically for precise analysis of flagellar kinematics, as that is the promising area for computer use.
