2014 Duke CFAR Flow Cytometry Workshop Data Standards and Annotation
2
What standards currently exist? International Society for the Advancement of Cytometry (ISAC) Data Standards Task Force (DSTF): Data file standards Flow Cytometry Standard (FCS) – version FCS 3.1 Gating ML Calibration and Measurement Standards Instrument calibration Fluorescence intensity calibrations Molecules of Equivalent Soluble Fluorescence (MESF) Antibody Binding Capacity (ABC) Equivalent Reference Fluorophore (ERF) Counting Standards Immunophenotyping Clinical cytometry standards MIFlowCyt: the minimum information about a Flow Cytometry Experiment Requirement for Cytometry publication Training and Education International Cytometry Certification Examination Flow Cytometry: International Cytometry Certification Examination Optimized ImmunoPhenotyping Panel (OMIP) Bioinformatics Standards for Flow Cytometry – working group Cellular Assays: Biosafety Biosafety in Microbiological Laboratories OSHA Bloodborne pathogens Risk Group and Biosafety Level Definitions Pathogen Safety Database Biological Risk Assessment Generic Form (CDCs) World Health Organization Laboratory Safety Manual ISAC Biosafety Standard for Sorting Unfixed Cells “Miata” Minimal Information about T Cell Assays

What is Annotation? Webster’s dictionary: Annotation: a note added by way of comment or explanation Wikipedia: An annotation is a note that is made while reading any form of text. These notes.. establishes a summary for and expresses the relevance of each source..
9
Why is it significant? A statistian can quickly batch analyze a large amount of information Data management: Metadata Data about data. Metadata describes how and when and by whom a particular set of data was collected, and how the data is formatted. Metadata is essential for understanding information stored in data warehouses and has become increasingly important in XML-based Web applications.Datadata warehousesXML Tracking Easily track which experiments/data are relevant Repository within a particular institution Institutions are interested in archiving data
10
Why is Annotation important?
11
Goal of Data Annotation John Altman: “…to include enough information within the FCS file to allow someone else to make sense of the data without requiring cross- references to your notebook.” - Another operator - Researcher - Investigator - Study Monitor - Auditor
12
Example of how not to annotate data No annotation of experiment: What’s in the experiment? No Annotation of data files: Which file is which? Where are the controls?
13
Data Annotation - for all 143,280 data points! Study ID Method Assay Name Batch # Operator Sample ID Visit ID Accession # % Viable (Flow) % Viable (Guava) Recovery CD4 count CD8 count Gate Name (Parameter Names) Tube Name File Name Checking: X1 - for electronic data X3 - for manual entry Requires STRONG statistical support: Quickly exceeds limits of excel Format data for statistical analysis FJ: column (gates) vs row (file) CSV: column (identifiers) vs row (single value) Check data Manual check: 8sec/value x 143280 = 49 days!!!

Keywords a word that serves as a key, as to the meaning of another word, a sentence, passage, or the like: Search the database for the keyword “Ireland.”wordkey Keywords can be entered into the data of a data file for easy searching within a database
