Hydrophobicity Grapher Quick Start

What is it? Hydrophobicity Grapher graphs the hydrophobicity/hydrophilicity of a sequence of amino acids, using a sliding window. The window size can be specified by the user, and several hydrophobicity scales can be used to determine the plot.

How do I get started?

  1. Select Hydrophobicity from the VBRC Tools drop-down menu (top left of page).
  2. Click the Launch Program button. Hydrophobicity Grapher will be downloaded to your computer and Java Web Start will automatically start the program.

Click here to go directly to the Hydrophobicity Grapher page.

What next? The Hydrophobicity Grapher window shown below will open. From here you can add sequences and view them using the different hydrophobicity scaling systems.

Because of how the plot is calculated, the very beginning and very end of the sequence will be cut off. The amount cut off will depend on the window size: exactly one half of the window size will be deleted from the beginning of the sequence, and the same amount will be cut off the end. Therefore, if one has a window size of 20, the first and last 10 amino acids will not be plotted.
