seq-seq-pan: building a computational pan-genome data structure on whole genome alignment

BMC Genomics

Table 1 Comparison of pan-genome tools. We analyzed tools for pan-genome analysis that are available or currently under development. This table lists the corresponding publications or websites. We compared the intended use cases of the tools and the prerequisite data required in order to use them. We evaluated the availability of features needed to work with the pan-genome in subsequent analyses, e.g. updating the set of included genomes. Furthermore, we assessed whether the proposed data structures take into account structural variants and whether it is possible to visualize the resulting pan-genome
