The Z’ factor, a measure of assay quality, is calculated by this module

controls and images that are specified as negative controls. Images
that are neither are ignored. The module assumes that all of the
negative controls are specified by a minimum value, all of the positive
controls are specified by a maximum value, and all other images have an
intermediate value; this might allow you to use your dosing information
to also specify the positive and negative controls. If you don’t use
actual dose data to designate your controls, a common practice is to
designate -1 as a negative control, 0 as an experimental sample, and 1
as a positive control. In other words, positive controls should all be
specified by a single high value (for instance, 1) and negative controls
should all be specified by a single low value (for instance, -1). Other
samples should have an intermediate value to exclude them from the Z’
factor analysis.

the column header of the measurement in the input file. See the main

(or the whole image if there is no mask) and rescale every pixel so that
the minimum has an intensity of zero and the maximum has an intensity of one.</li>
<li><i>%(M_MANUAL_INPUT_RANGE)s:</i> Pixels are
scaled from their user-specified original range to the range 0 to 1.
Options are available to handle values outside of the original range.<br>
To convert 12-bit images saved in 16-bit format to the correct range,
use the range 0 to 0.0625. The value 0.0625 is equivalent
to 2<sup>12</sup> divided by 2<sup>16</sup>, so it will convert a 16 bit image containing
only 12 bits of data to the proper range.</li>
<li><i>%(M_MANUAL_IO_RANGE)s:</i> Pixels are scaled from their original range to
the new target range. Options are available to handle values outside
of the original range.</li>
<li><i>%(M_DIVIDE_BY_IMAGE_MINIMUM)s:</i> Divide the intensity value of each pixel
by the image's minimum intensity value so that all pixel intensities are equal to or
greater than 1. The rescaled image can serve as an illumination correction function in
<b>CorrectIlluminationApply</b>.</li>
<li><i>%(M_DIVIDE_BY_IMAGE_MAXIMUM)s:</i> Divide the intensity value of each pixel by the
image's maximum intensity value so that all pixel intensities are less than or equal to 1.</li>
<li><i>%(M_DIVIDE_BY_VALUE)s:</i> Divide the intensity value of each pixel by the value entered.</li>
<li><i>%(M_DIVIDE_BY_MEASUREMENT)s:</i> The intensity value of each pixel is divided by some
previously calculated measurement. This measurement can be the output of some other module
or can be a value loaded by the <b>Metadata</b> module.</li>
<li><i>%(M_SCALE_BY_IMAGE_MAXIMUM)s:</i> Scale an image so that its maximum value is the
same as the maximum value within the reference image.</li>
<li><i>%(M_CONVERT_TO_8_BIT)s:</i> Images in CellProfiler are normally stored as a floating
point number in the range of 0 to 1. This option converts these images to class uint8,
meaning an 8 bit integer in the range of 0 to 255,
reducing the amount of memory required to store the image. <i>Warning:</i> Most
