Hello,
The CSI in Analysis is some combination of the CSI results for H and C and
so the way the index is calculated is somewhat homegrown (so determining
the consensus across the various indices for a given residue).
Having said that, there was a typo in the code so that the index for Tyr
was not being calculated at all, so I've fixed that. I also changed it so
that the index comes out to 0 if it is not set to something else, as long
as there is an assignment for at least one of the C/CA/CB/HA. The code
will still report None (i.e. blank) if there are no assignments, but that
should be the only time that happens now.
