Percentage of Data on M Component to Be Trimmed

Use this text box to specify the percentage of data to be trimmed on the M component (y-axis of the MA Plot) before normalization. The half percentage of data with upper and lower M values are trimmed. Trimming in this way reduces the chance that counts that differ greatly between the sample and baseline could skew the normalized values.

For example, a value of 30 specifies that the lowest 15% and highest 15% of the values on the M component are to be removed from the normalization process.

To Specify the Percentage of M Component Data to Be Trimmed:

8      Type the desired value in the text box.
