Dinamički FM-indeks jest poboljšana verzija potpunog i samostojećeg FM-indeksa. Dinamički FM-indeks je struktura podataka često korištena u bioinformatici jer omogućuje učinkovito traženje podniza u tekstu koji može biti mijenjan tijekom vremena. Opisana verzija dinamičkog FM-indeksa bazira se na dinamičkoj Burrows-Wheelerovoj transformaciji i dinamičkim stablima valića.Dynamic FM-index is an improved version of the full-text and stand-alone FM-index. Dynamic FM-index is a data structure often used in bioinformatics because it allows efficient search of the substrings in a text that can be changed over time. Described version of the dynamic FM-index is based on a dynamic Burrows-Wheelers transformation and dynamic wavelet trees
