Hi -- I'm having this issue when trying to run Banks to Centerline and Centerline Migration in QGis 3.6.3:

[1] "C:/Program Files/R/R-3.5.3/library/sf"
Linking to GEOS 3.6.1, GDAL 2.2.3, PROJ 4.9.3
[1] "C:/Program Files/R/R-3.5.3/library/raster"
Loading required package: sp
Error in identicalCRS(Original, Final) :
unable to find an inherited method for function 'proj4string' for signature '"sf"'
Calls: stopifnot ... tryCatch -> tryCatchList -> tryCatchOne ->
Execution halted

I've double-checked in R to have all the packages installed and updated, but still got the same result. Tried different files (some of them already analyzed some times ago).
Thanks

Hi,
Is this available as a plugin in QGIS. I couldn't find much documentation.

Can you please help me in this regard?

Thanks

Hi, I am getting the following message when trying to run Channel Migration:

Performing alignment...
Error in dtw(with(from.df, data.frame(x, y, Curvature * Curvature_multiplier)), :
No warping path exists that is allowed by costraints
Calls: lapply -> FUN -> dtw
Execution halted

It seem like it depends on the centerline shapefile I am using: some of them work just fine, while some others don't. However, I cannot figure out what the differences are, and so why the code doesn't work sometimes.

Polyline features (see attached file) are single-part and oriented in the same way.
I am using QGIS Wien 2.8.9 (didn't get the tools to work on more recent versions).

Best
