Welcome to an updated version of qteller! Compare RNA & Protein

Two-Gene Scatterplot Advanced Options

NOTE: B73 v4 Visualize Expression accepts only v4 gene IDs (Zm00001), not classical or GRMZM IDs. To convert your GRMZM IDs to v4, go HERE.

Gene1 Name:
Gene2 Name:

Try comparing the expression of these two genes Zm00001d000002 and Zm00001d000001

qTeller takes a little while to generate figures. Don't panic it nothing happens for 30 seconds after you click Submit.
