G/C content along sequences

You can analyze the G/C content of a part of the sequence, showing it as a gradient of colors and/or as a graph below the sequence.

Available user options:

  • Window length. Determines the length of the part of the sequence to calculate. A window length of 9 will calculate the G/C content for the nucleotide in question plus the 4 nucleotides to the left and the 4 nucleotides to the right. A narrow window will focus on small fluctuations in the G/C content level, whereas a wider window will show fluctuations between larger parts of the sequence.
  • Foreground color. Colors the residues depending on the G/C content. Two sliders allow you to choose a lower threshold and an upper threshold.
  • Background color. Sets a background color of the residues using a gradient in the same way as described above.
  • Graph. If you would like the G/C content shown as a graph, these user options are available:
    • Graph height
    • Graph type (Line plot/Bar plot/Color bar)
    • Graph color
