[NSRCA-discussion] F3A: F21 observations

Tue Nov 26 10:48:13 AKST 2019

As long as we're discussing the new sequences -- I added them to the
RCCaller app's online library of sequences as <className>-2020.  If you use
RCCaller and hit the sequence refresh button in the upper right corner
(circle arrow icon) you should see them.  If you do not, it could be
related to customizations you have to older sequences and/or the presence
of generated unknowns -- I have a bug in the sequence reconciliation I need
to figure out.  In the meantime, if you refresh and don't see the -2020
sequences, delete the app and re-install it and it will pull a fresh copy
of the sequence library and you will have the latest sequences.
