Q1. How to handle the situation when there are divergences between a GenBank file and an actual or theoretical molecule:
Should the difference be indicated in the feature table? If so, with which feature key? And if not, how should it be indicated or what should be done?
Further, when indicating a divergence withusing a feature key, which should be considered the reference: the file or the molecule?
Q2. How to keep track of changes between versions of a GenBank file when corrections or updates are made?
I have thus re-titled the question accordingly.
Also, and by making further researches into the issues, I found what seems to me the appropriate solutions (see my answermy answer below).
