Hi Mark, Bioconductor graphs (graphNEL, graphAM, ?) have to be either directed or undirected: no hybrid graphs are possible. If I understand your question, this can be worked around quite easily, both in a graphNEL object and in its display in RCytoscape. See the sample code below. The current design of graphNELs includes a penalty for undirected graphs: every edge is stored twice. Until we fix that, RCytoscape does best with directed graphs only. Let me know if this helps. - Paul library(RCytoscape) g <- graphNEL(edgemode="directed") g <- initNodeAttribute(g, "label", "char", "unspecified") g <- initEdgeAttribute(g, "edgeType", "char", "unspecified") g <- addNode(c("A","B"), g) # comment this next line to see one-way regulation between B and A # leave it live to see reciprocal regulation # edge target rules, below, display differently in the two cases g <- addEdge("A", "B", g) edgeData(g, "A", "B", "edgeType") <- "regulation" nodeData(g, nodes(g), "label") <- nodes(g) # now add a regulatory relation between B and A # check first to see if A already regulates B if("B" %in% edges(g)$A) { edgeData(g, "A", "B", "edgeType") <- "reciprocal regulation" } else { g <- addEdge("B", "A", g) edgeData(g, "B", "A", "edgeType") <- "regulation" } cw <- new.CytoscapeWindow("demo", g, overwriteWindow=TRUE) displayGraph(cw) layoutNetwork(cw, "jgraph-spring") setNodeLabelRule(cw, "label") setEdgeTargetArrowRule(cw, "edgeType", c("regulation", "reciprocal regulation"), c("Arrow", "Arrow")) setEdgeSourceArrowRule(cw, "edgeType", c("regulation", "reciprocal regulation"), c("No Arrow", "Arrow")) redraw(cw) On Dec 5, 2012, at 11:30 PM, Mark Christiansen wrote: > Hi Paul, > > I have been using your examples in the RCytoscape package to build up a gene network.

This means that RCytoscape support for Cytoscape 3 has to wait until the protocol and the 'commands' API are both well-defined. Jan Bot, who wrote CytoscapeRPC, suggests that this is a big job and won't happen for a while. > > Until then, maybe you can get by with the venerable Cytoscape 2.8.3? > > - Paul > > On Nov 19, 2012, at 10:37 AM, Mark Christiansen wrote: > > > Hi Paul, > > > > It seems the same Plug-In Manager to install CytoscapeRPC is not available on Cytoscape v3. Has this been replaced by the Apps Manager?

I was trying to install XML-RPC manually from source and ran into some difficulty. I just tried installing CytoscapeRPC via the Cytoscape plug-in manager and it worked like a charm. > > > > Thanks again! > > > > -Mark > > > > > > On Sun, Nov 18, 2012 at 8:21 PM, Paul Shannon <pshannon at="" fhcrc.org=""> wrote: > > Hi Mark, > > > > The RCytoscape package should install fine on Windows. XML-RPC and its prerequisite XML work on Windows. Maven is not needed, not unless you are building Cytoscape from scratch, and not necessariliy even then. The installation instructions avaialable at http://rcytoscape.systemsbiology.net should get you going. > > > > If not, could you give us the results of sessionInfo ()?
