A fellow of mine sent me some code to open a workflow:
public class ServiceMapBuilder {
public ServiceMapBuilder(){}
// fileLocation :: ""C:/Documents and Settings/admin/My
Documents/Downloads/_lymphoma_type_prediction_based_on_microarray_data__547084.t2flow"
public void openWorkflow(String fileLocation){
File fileObject = new File(fileLocation);
FileManager fileManager = FileManager.getInstance();
try {
fileManager.openDataflow(new T2FlowFileType(), fileObject);
} catch (OpenException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("Did we make it?");
}
}
When I run it, I get the following error:
