-The naming scheme of assembly should follow <a href="https://github.com/pangenome/PanSN-spec">PanSN prefix naming pattern</a>. Briefly, the assembly’s name consists of sample name, delimiter, and haplotype name, e.g., sampleA#0. But it’s a little looser in VRPG. It’s not required that the haplotype name must be numeric, characters are also allowed. The assemblies to graph mapping files are also required. If these files do not exist the assembly can’t be highlighted in the drawing. These files can be generated by minigraph by using command ‘-cxasm --vc’. Then run the following command to get files required by VRPG.
