This error comes in a few forms (where the parameters usually change (different tcplfit2 models). Occurs in levels 4 and 5.

Error in uniroot(acgnlsobj, c(toploc, 1e+05), y = y, tp = tp, ga = ga,  : 
  f() values at end points not of opposite sign

These warnings occured when processing level 5 of aeid 759 and seem to be also caused by tcplfit2.

Warning: There were 549 warnings in `mutate()`.
The first warning was:
ℹ In argument: `df = list(...)`.
ℹ In row 55.
Caused by warning in `sqrt()`:

This may be a tcplfit2 ticket consider adding verbose = FALSE as default and supress these messages and user can add verbose = TRUE to show all
