Glossary Glossary of Terms
interquartile range, standard deviation) can be printed out in the Region Statistics
window.
stepper
A device that controls moving the microscope stage.
controller
stochiometric Measurements that are proportional to the amount of substance present.
Stokes shift The wavelength difference between the light absorbed by a fluorochrome and the
light emitted during fluorescence.
T
tab A tab is a way of moving within a dialog box. (Use the TAB key.)
A group of tabs along the top of a dialog box provide you with subcategories of
options.
taskbar In Windows XP, a taskbar is a horizontal bar located at the bottom of your screen.
A button on the taskbar indicates a program that is open.
In iCys, the Taskbar displays standard tasks, usually on the right-hand side of the
iCys window.
text box An area in a dialog box where the user can enter text.
texture The measure of the variability of fluorescent intensity of a cell. Cells that have
increasing pixel values from the cell’s edge to the peak have a relatively low
texture value. Cells that have undulating pixel values have relatively high texture
measurements.
threshold An instrument setting that is used to determine a boundary based on the intensity
of the photodetector signals. The threshold assists the user in making the optimum
instrument settings. Once these settings are made, the measurements on those
events can be saved for later analysis.
.TIF file (Tagged-Image File Format) A bitmap graphics file of an image.
tissue
A slide that contains many small pieces, or cores, of sample tissue. Using the
microarray iNovator Application Development Toolkit, you can use iCys to label and scan
tissue array samples.
title bar The horizontal bar at the top of a iCys window that displays a label for the
contents of the window.
toolbar An area on the desktop used to place icons. The icons placed in the toolbar can be
customized by the user.
torus An area bounded by two user-defined contours. It is used to determine the amount
of fluorescence around the perimeter of a cell and also for calculating the amount
of background fluorescence.
2-parameter A color plot of the values of two user-selected parameters with color representing
histogram
either the density or an expression. 2-parameter histograms are set from the
Scattergram menu in iCys.
