3.
The next entry field is used to enter the condition for the elimination. For example individual
positive controls should be eliminated which are deviating more than 15% from the mean
value. The condition is entered as following:
X > avg(PC) *1.15 | X < avg(PC) *0.85
X represents any single well of the positive control well, the ‘|’ stands for a logical or.
4.
The formula can be read as: If as single
positive control is higher than 115 % of
the mean value of the positive control or if
a single positive control is lower than 85 %
of the mean value then eliminate the
respective single positive control.
5.
When the cursor is in the entry field the function keys are active and users can select different
options. There are three groups of elements that can be selected by pressing the F1 (Alt) key:
Controls (single and average) and the factors.
Op, -, /, etc.
All available mathematical and logical functions.
6.
Use F2 and F3 to select the desired element and F4 to place it.
3.7.2.9 Method Definition: Transformation
Use this option to define a calculation equation to be applied to each well. All typical mathematical
functions are available (+ /- , sqr, abs, log, log10, x², etc.) and Pow (power of x).
