Error in identifying root and end points use the Markov random-walk model. Help!

[yanwengong]

I am trying to identify root and end points use the Markov random-walk model with the rna velocity package. The plot I want to generate is Fig.3C Diffusion and Back-diffusion part in the paper.

I tried running show.velocity.on.embedding.eu(emb, rvel.cd_bs,n=500,scale='sqrt',show.trajectories = TRUE), but get error in " # cluster paths" part: Error in t.default(spuci) : argument is not a matrix

I wonder how should I fix it? Do I need to go to the source code to convert spuci into matrix?

Thanks for any help!!

Hi @yanwengong, I am interested in getting diffusion plots with root and end points as in fig3c, and wondered if you have found a solution. Thank you.
