... is:
A) the title of one of the "Dr. Seuss" books (you would know if you have lived with children in pre-school age in the U.S.)
B) an editorial aricle by Michelle LeBeau
To not stick too much to the green=gain | red=loss color scheme (compared to the strange but widely used red=high expression etc. scheme of the expression array community), today two radical changes took place:
1. yellow is the new green, blue is the new red (therefore accommodating people with color recognition problems, though we already did refrain from pure red/green ...)
2. ideograms are plotted by new routines, implemented in R: larger chromosomes, better level lines, PNG + PDF vector graphics (after the links); however, no single band links to USCC anymore (you either know how to get there, or you want a data analysis collaboration).
Enjoy,
Michael.
