Intuitively, if two strings S1 and S2 are sufficiently similar and we already have an FM-index for S1 then, by storing a little extra information, we should be able to reuse parts of that index in an FM-index for S2. We formalize this intuition and show that it can lead to significant space savings in practice, as well as to some interesting theoretical problems.
