- | For example, the BWT of the string T = "abracadabra" is "ard$rcaaaabb", and here it is represented by the matrix M where each row is a rotation of the text that has been sorted. The transform corresponds to the last column labeled L. | + | An FM-index is created by first taking the Burrows-Wheeler transform (BWT) of the input text. For example, the BWT of the string T = "abracadabra" is "ard$rcaaaabb", and here it is represented by the matrix M where each row is a rotation of the text that has been sorted. The transform corresponds to the last column labeled L. |
