Creating an annotation entry

At the end of the annotation, we need to create a new MS Annotation Entry and add that as a child entry for the corresponding MS Entry and save the project (that contains the MS Entry) to make changes permanent.

Several steps are included in this process (see

  1. Create a new Entry and set its display name: In the example below, we are getting the name from the wizard where a user enters a name for the annotation for each MS entry that is annotated.
        Entry msAnnotationEntry = new Entry();

        String msEntryDisplayName = msEntry.getDisplayName();
        String msAnnotName = wizard.getInitial().getListEntries().get(msEntryDisplayName);
  1. Creating the property: We need to know the annotation folder to be able to assign a unique annotation id to the metadata in the property. "createRandomId" does the following: randomly generate an id and check to make sure it does not exist in the folder already.
        // getting the annotation folder
        File msAnnFile = getAnnotationFolder(msEntry);	
        String msAnnotationFolder = msAnnFile.getAbsolutePath();

        MSGlycanAnnotationProperty t_property = new MSGlycanAnnotationProperty();
        MSGlycanAnnotationMetaData metaData = new MSGlycanAnnotationMetaData();		
        msAnnotationEntry.setProperty (t_property);        

Getting the annotation folder for the given ms entry:

        protected File getAnnotationFolder( Entry msEntry ) {

		String workspaceLocation = PropertyHandler.getVariable("workspace_location");
		MSGlycanAnnotationProperty t_property = new MSGlycanAnnotationProperty();
		Entry projectEntry = DataModelSearch.findParentByType(msEntry, ProjectProperty.TYPE);
		String projectName = projectEntry.getDisplayName();

		String msAnnotationFolder = workspaceLocation + projectName + File.separator + t_property.getArchiveFolder();	
		File msAnnotationFolderFile = new File(msAnnotationFolder);

		return msAnnotationFolderFile;
  1. Creating the data files and linking them to the metadata created in the previous step:
        Data data = new Data();
	DataHeader dHeader = new DataHeader();
	data.getDataHeader().setMethod(somemethod);     // somemethod is the Method object initialized in the wizard with all the different annotation settings

During annotation this data file is populated with annotation information and written to the file (see

  1. Saving the metadata and annotation files
            // if everything worked, save to workspace all of the appropriate files for Annotation
    	msAnnotProperty.getMSAnnotationMetaData().addAnnotationFile(dataFile);      // dataFile is the file we have used for annotation (a handle (MSPropertyDataFile) to the mzxml file for example)
    	PropertyDataFile msMetaData = MSAnnotationProperty.getNewSettingsFile(msAnnotProperty.getMetaDataFileName(), msAnnotProperty.getMSAnnotationMetaData());
    	addResultFileToMetaData(dHeader.getMethod().getMsType(), msAnnotProperty);
    	MSAnnotationProperty.marshallSettingsFile(msAnnotProperty.getAnnotationFolder(msEntry) + File.separator + msAnnotProperty.getMetaDataFileName(), msAnnotProperty.getMSAnnotationMetaData());
        protected void addResultFileToMetaData(String sMSType, MSAnnotationProperty msAnnotProperty) {
		if( sMSType.equals(Method.MS_TYPE_LC) ) {
			NewGelatoHandlerLCMSMS.addResultFileToMetaData(gsa, (MSGlycanAnnotationProperty) msAnnotProperty);
		} else {
			NewGelatoHandler.addResultFileToMetaData(gsa, msAnnotProperty);

	 * Determines the annotation file name and folder name (if applicable), creates MSPropertyDataFile objects for them, and adds
	 * them to the meta data for the result files.
	 * @param gsa, the GlycanStructureAnnotation specific for the MS Type other than LC-MS/MS
	 * @param msAnnotProperty, the Property to add the results file to
	private static void addResultFileToMetaData(GlycanStructureAnnotation gsa, MSAnnotationProperty msAnnotProperty) {
		String sAnnotationFile = gsa.getFinalArchiveName();
		File annotationFile = new File( sAnnotationFile );
		MSPropertyDataFile pdfFolder = new MSPropertyDataFile(annotationFile.getName(), 
				annotationFile.getPath(), new ArrayList<String>() );

  1. Saving the entries. (see
              gritsDataModelService.addEntry (msEntry, msAnnotationEntry);
              // parent of MS Entry is Sample, parent of Sample is the Project
  1. Locking the annotation files since they are now used in an annotation. This allows us to mark (annotation) files as "in use" in MS entry display. (see
        private void lockFiles(MSGlycanAnnotationWizard wizard, Entry msEntry, Entry msAnnotationEntry) {
		MassSpecProperty prop = (MassSpecProperty) msEntry.getProperty();
		FileLockManager mng;
		try {
			String lockFileLocation = prop.getLockFilePath(msEntry);
			mng = FileLockingUtils.readLockFile(lockFileLocation);
			MSPropertyDataFile file = wizard.getInitial().getFileMap().get(msEntry.getDisplayName());
			if (file != null) {
				mng.lockFile(file.getName(), msAnnotationEntry);
				FileLockingUtils.writeLockFile(mng, lockFileLocation);
		} catch (IOException e) {
			logger.error("Could not lock the file", e);
		} catch (JAXBException e) {
			logger.error("Could not lock the file", e);

  1. Opening the editor to display the annotation results (see
try {
	// need to set the partService to refresh gritsUIServices' stale partService, see ticket #799
} catch (Exception e) {
	logger.debug("Could not open the part", e);
