Accuracy & Statistics
The PCMass software includes a folder of practice images for use with the tutorials.
We recommend the tutorials as a starting point before beginning analysis of your own data.
The PCMass manual includes additional details about the internal operation of the software, but is
not essential for normal analysis.
