package "wmtsa": how to set up the Tolerance vector to detect time series peaks blindly
In my previous experience with wmtsa function wavCWTPeaks I realized the Tolerance vector passed to the multi-scale decomposition function "wavCWTTree" is crucial for detecting the time series extrema and prevent the R script from aborting.
By trial & error I recently managed to figure out the Tolerance vector values in a single case (please see attachments).
I am looking for some

WMTSA "wavCWTPeaks" : Error in if (time.start < times.range[1]) time.start <- times.range[1]
I have attached the signal that causes the error message in this email subject.
Only columns 1 and 3 have to be considered. It is the work trajectory of a molecule migrating between two equilibrium conformations.
The curve has 2 peaks, as shown in its plot. But I keep missing the 2nd one. Here is my short script:
library(wmtsa)

wmtsa (wavCWT)
I can send data along, but it is too large for the list:
I am using wmtsa and the function wavCWT
I would like to use the range.scale to only evaluate a subset of
frequencies.
deltat of the time series that I am trying to analyze is 1
d = wavCWT(RM202.ts, range.scale = c(96, 2688))
and I get the error message
Error in wavCWT(RM202.ts, scale.range = c(96, 2688) :
Minimum scale must be greater

package "wmtsa": wavCWTPeaks error
I keep getting the following error when I look for minima in the series:
> aa.peak <- wavCWTPeaks (aa.tree)
Error in `row.names<-.data.frame`(`*tmp*`, value = c("1", "0")) :
invalid 'row.names' length
How can I work it around ?
Thank you.

Is there anyone in charge of package wmtsa ?
Here is another occurrence of wmTSA internal error.
My time series is a short breathing cycle (2425-Cyle_9.txt).
Since wmtsa functions that extract extrema seem to expect longer series than I have, I tried the folowing two tricks:
1) I prolong the 1-cycle series on both ends through duplicating the first value (on the left end( and the last value on the right end as any ties as the
1-cycle
