· about · create · examples · manual ·

Various tests of the WebLogo webapp.

Relative Entropy Test
  The entropy should be 2 bits, 1 bit, 0 bits (The small sample correction should be turned off.)
Title And Labels Test
  Replace and display x-label, y-label and title. Same, but do not show axes
Format Test
  Ensure that this logo can be created in each of the available formats Format:
Test Alphabetic Order
  Each character in each stack has the same entropy. The letters should be alphabetized, top down. (NA) (AA)
One Single Column
  Should not die just because there is only 1 stack.
Small Sample Correction Test
  The samples per column decrease from 32 (left) to 1 (right). Before the small sample correction the relative entropy of each stack is 2 bits.
Test Graceful Failure
  Each of these tests should result in a polite and informative error message.
Logo Sizes
  Same sequences, three different sizes. Size:
