  • Section evaluation interval: Interval of the serially cut sections that you are going to count.
    • To count every other section, enter 2.
    • To count every third section, enter 3, etc.
  • Starting section number: Number of the first section you start from in your serial sections
    • The first sampling section should be randomly selected.
    • If you don't want to keep track of the section count from the microtome, leave this number as "1."
  • Z-value of first section: This number is automatically adjusted based on the Starting Section Number entered before; it reflects an interval of the cut thickness.
