Function Documentation

graph2amiraSpatialGraph()

function res = graph2amiraSpatialGraph	(		filename,
			G,
			options )

generate Amira Spatial Graph Ascii file

Parameters

filename	filename to save data
G	a standard matlab graph object, see graph function for details, with the following properties .Nodes - a table with following columns, .XData - x coordinate of the node .YData - y coordinate of the node .ZData - z coordinate of the node .PointsXYZ - alternative way (instead of XData, YData, ZData) to specify the points. In this case is is a matrix [nodeId][x,y,z] .Values - [optional] values for the nodes .Edges - a table with following columns, .EndNodes - connectivity matrix for the nodes starting from 0 .Points - [optional] a cell array with coordinates of points for each of the edges, in minimalistic case should have at least 2 points, starting and ending; format {edgeId}[pointId, x y z] .Thickness - [optional] a cell array with thickness at each point of a node; format {edgeId}[pointId, thickness]
options	- a structure with additional options .overwrite - 1-automatically overwrite existing files .format - a string with format: binary or ascii .NodeFieldName - a cell array (max 2 elements) that specify which Field in the .Nodes to export, in this case Nodes.Values is not needed .EdgeFieldName - a cell that specify which Field in the .Edges to export, in this case Edges.Thickness is not needed

Return values

res	result of the function run, 1 - success, 0 - fail

Required fields of G:

Examples:

G = graph([1 2 4],[2 3 5]);   // creates a graph with five nodes and three edges: 1-2-4 and 3-5
G.Nodes.XData = [1 2 3 4 5]';  // x coordinates of each node
G.Nodes.YData = [5 4 3 2 5]';   // y coordinates of each node
G.Nodes.ZData = [1 3 4 2 5]';  // z coordinates of each node
G.Nodes.Values = [1 2 4 2 5]';  // value for each node
G.Nodes.Values2 = [5 4 3 2 1]';  // optional second value for each node
G.Edges.Thickness = ones([size(G.Edges,1) 1]);  // thickness value for the edges
figure(1);  // test results
p = plot(G); 
p.XData = G.Nodes.XData;
p.YData = G.Nodes.YData;
p.ZData = G.Nodes.ZData;
options.NodeFieldName = [{'Values'}, {'Values2'}]; // name of variables that should be exported for nodes
options.EdgeFieldName = {'Thickness'};    // name of variables that should be exported for edges
res = graph2amiraSpatialGraph('test.am', G, options);    // save to a file
