Hi there, you can check our new package treescape (still unpublished) to do exactly that, and more. https://github.com/thibautjombart/treescape Cheers Thibaut == Dr Thibaut Jombart MRC Centre for Outbreak Analysis and Modelling Department of Infectious Disease Epide

[R-sig-phylo] 3 dimensional ordination of tree distances

2015-11-30 Thread Chris Buddenhagen
Is there a way to plot gene tree similarities in 3D ordinal space? I want to identify groups and outliers for hundreds of gene trees. I am pretty happy with TreeCmp (java program and graphing distances in ggplot) but I'd be keen to see this in a more multi-dimensional format. Cheers Chris Budden

Hi Saurabh, I have some R code to fit BM with two reflective bounds (not absorbing ones). I don't know how this compares to what Brian suggested. The paper describing the model is in review, but the code has been tested and inference has reasonable performance. The model can be compared to other u

There's alpha code to do this in TreEvo, but we're still readying this for publication (and it's now supported by an NSF grant, so expect much more development), and so I wouldn't advise using it yet. I don't know of anything else at the moment. Best, Brian __

Hello, does anyone know if its possible and how to fit Brownian evolution with either reflecting or absorbing boundaries? And many thanks for creating this excellent resource! Saurabh -- Saurabh Mahajan Research Scholar/Graduate Student Deepa Agashe's Lab National Center for Biological Scienc
