This is a section of your contigs-db that contains custom additional information about specific nucleotides.

Take a look at this blogpost for potential uses in the InteracDome (which will likely be added to anvi’o in v7) and the motivation behind this program.

Similarly to other types of miscellaneous data (like misc-data-items), this information is either numerical or categorical and can be populated into a contigs-db (from a misc-data-nucleotides-txt) with anvi-import-misc-data. It is also displayed when you run anvi-show-misc-data and can be exported or deleted with anvi-export-misc-data and anvi-delete-misc-data respectively.

For example, this information could describe specific nucleotides that are known to be SNVs from another experiment, various key nucleotides for binding to ligands, or positions known to have other modifications (such as m1A or s4U).
