I have a Mathematica notebook that sometimes uses one set of definitions and sometimes other definitions for the same function and string names. I tried putting one set of them in a notebook and then used SaveAs to create a .m file. I then tried to...
When a Graph is generated with layout "LayeredEmbedding", is there a built-in means of obtaining lists of vertices per layer, in horizontal order (e.g. left to right)? ![enter image description here][1] [1]:...

Hi, I'm working with Wolfram on some genetic distance measures for SSR profiles of perennial crops. One of the measures requires known absolute or relative positions of the SSR marker loci. Another statistically estimates the positions based on a...
Version 1 for adjacency matrix input. See below for tabular data input. Error reports and general feedback welcome. &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/1675099c-2240-4a55-b487-ed2e4870e5ee
Here's a scaled-down example. I have graphs with weighted edges that I'd like to use in NearestNeighborGraph, Dendrogram, ClusteringTree, etc. So far I've only had success with Graph[] and GraphDistance[]. vertices = {"A", "B", "C", "D"} ; ...
So far I've been able to produce dashes on an undirected edge: Graph[{1 -> 2, 3 \[UndirectedEdge] 1, 3 \[UndirectedEdge] 2}, EdgeStyle -> {3 \[UndirectedEdge] 1 -> Dashed}, VertexLabels -> All, ImageSize -> Small] a...
Is there a function to concatenate a 1-dimensional list of same-size, same colorspace images into a single image? For example, how to concatenate list simeonRast into a {156, 56} image: simeonRast = Table[Rasterize[Style[StringPart["Simeon",...
Hi, I've a background in color theory from years ago but the last time I used Mathematica was probably v.2. My concern is with colors, not images. I've been reading and experimenting with the documentation here:...
