1. A method comprising: determining a maximum shift value of a set of one or more shift values for re-aligning a two-dimensional data set, wherein each of the set of one or more shift values indicates shifts at a specified index into a first dimension of the two-dimensional data set, wherein the two-dimensional data set is compressed along the first dimension; for each second dimension vector of the two-dimensional data set, determining whether shifting for each of the set of one or more shift values at the specified index into the first dimension of the second dimension vector results in a different vector than either a previously created vector or the second dimension vector; if shifting results in the different vector, adding the different vector to a re-aligned array; if shifting does not result in the different vector, incorporating a compressed form of the second dimension vector into the re-aligned data set.
