CytoscapeをPHPで動かす

Tweet

Pocket

perl から Cytoscape を扱えることはperlからCytoscapeを利用し、jpegに保存の通りできることがわかった
しかし、使う言語ってphpかCのどちらかなんですよね
皆さんはどうでしょう？
今回は perl で書かれていたサンプルプログラムをPHPにしてみました

ソースはこちら

<?php

        require_once("XML/RPC2/Client.php");

        $options = array(
                "prefix"        => "Cytoscape."
                );

        $client = XML_RPC2_Client::create("http://localhost:9000/Cytoscape",
                                        $options
                );

        $networkID = $client->createNetwork("PHP Test Network");

        $networkTitle = $client->getNetworkTitle((string)$networkID);

        print $networkTitle . "\n";

        $done = $client->createNodes(array("a","b","c","d","e","f","g"));

        print "Done adding nodes."."\n";
        $nrNodes = $client->countAllNodes();
        print "There are now ". $nrNodes. " nodes present in Cytoscape"."\n";

        $done = $client->addNodeAttributes(
                        "str",
                        "STRING",
                        array(

        $done = $client->addNodeAttributes(

                        ),
                        true
                );

        print "Adding edges."."\n";

        $from = array("b", "b", "c", "d", "d", "d", "d");
        $to =   array("b", "c", "d", "a", "e", "f", "g");

        $directed = array(true,true,true,true,true,true,true);

        $done = $client->addEdgeAttributes(

                        $edge_attrs
        );



        // Set node selection
        $done = $client->setSelectedNodes(
                        $from

                                'cc' => 'rect'

                );

        $done = $client->createContinuousNodeVisualStyle(

        $done = $client->exportView(

                        2.0
        );

        print "\n";
?>

当初、実行したら下のようなエラーが出てexportView() の所が動かなかった

PHP Fatal error:  Uncaught exception 'XML_RPC2_FaultException' with message 'No method matching arguments: java.lang.String, java.lang.String, java.lang.String, java.lang.String' in /usr/share/pear/XML/RPC2/Backend/Xmlrpcext/Client.php:126

exportView() の 2.0 の所を下のようにダブルクォートで囲っていた

        $done = $client->exportView(
                        (string)$networkID,
                        "/tmp/hoge.jpg",
                        "jpg",
                        "2.0"
        );

perl の方は動いてたので、perl.pl を実行してwireshark でパケット見てみた
exportView() のリクエストで 2.0 がdoubleタグで囲まれてた
phpのソースから exportView() の 2.0 についてたダブルクォート抜いたら動いたよ
