How to Use PSICQUIC Client in Cytoscape 2

Install Plugin

The PSICQUIC Client Plugin is compatible with Cytoscape 2.7.0 or later. If you have older versions, please download the latest version. The Plugin is available from Cytoscape Plugin Manager. Select Plugin-->Manage Plugins and then you can find the plugin under Network and Attribute IO section --> PSICQUICUniversalClient

Start Plugin

To start the plugin, select the client from File-->Import-->Network from web services.... If PSICQUIC client is properly installed, you can find it in Data Source combo box.

Query Services

There are two search modes in the client:

  • Search by Interactor ID
  • Search by Query (MIQL)

You can switch the mode from Search Property tab.

Search by Interactor ID(s)

In this mode, Cytoscape sends list of identifiers as query. You can simply copy and paste list of identifiers to the text box. After the search process, it pops up a window, where you can select which data sets you want to import. If the result is 0 or the service is inactive, it will be ignored. When the import process is finished, you also have the option to edit the network titles if you want. If you press the Merge button, the Advanced Network Marge plugin will be started and you can merge imported networks manually.

Search by MIQL

This mode supports MIQL syntax. You can simply type the query in the text field. For more information about MIQL, please read the reference page.
