TUTORIAL 1
Introduction to CellProfiler, Free Open-Source Software for Image Analysis


Instuctors:
Kyle Karhohs, Broad Institute
Beth Cimini, Borad Institute

Course overview: Microscopy experiments have proven to be a powerful means of generating information-rich data for biological applications. From small-scale microscopy experiments to time-lapse movies and high-throughput screens, automatic image analysis is more objective and quantitative and less tedious than visual inspection. This course will introduce users to the free open-source image analysis program CellProfiler and its companion data exploration program CellProfiler Analyst.  We will show how CellProfiler can be used to analyse a variety of types of imaging experiments.  We will also briefly discuss the basic principles of supervised machine learning with CellProfiler Analyst in order to score complex and subtle phenotypes.
Outline:
•    Basics of image analysis
•    Methods of distinguishing objects of interest from the image background
•    Methods of separating clusters of touching objects
•    Obtaining measurements from the cell 
•    Exporting measurements and images

“You Can Lead a Horse to Water…” Flow Cytometry Myths Which Still Exist

Instructors: 
Evan Jellison, Department of Immunology, UConn Health 
Ryan Duggan, Oncology Discovery, AbbVie, Inc.

 
Do you have a stubborn student, post-doc, or principal investigator? Have you ever heard, “I’ve always done it this way and it just looks better” or “that’s how our lab has always done it”? From appropriately setting detector voltages to using the proper controls for compensation and gating, flow cytometry can be a complicated enterprise. It’s all too easy to fall back on what works for you or what makes your P.I. happy.
 
This tutorial will discuss common myths which still exist in flow cytometry and arm attendees with the tools to dispel these myths using actual examples. While the origins of these myths may never be known, their conclusion starts with you.

TUTORIAL 12
Optimize Your Flow Cytometry - Best Practices for Sample Preparation and Staining

Instructor:
Ruud Hulspas, Cellular Technologies Bioconsulting, LLC

Background:
Non-specific binding of antibodies can obscure data interpretation and even hide cell populations of interest. Aside from the quality of antibodies, sample preparation methods greatly affect the way antibodies bind to their intended, as well as unintended targets.

Content:
This Tutorial considers various kinds of ‘background’ in flow cytometry and explains how each kind can be controlled/minimized. Topics include:
  • Antibody performance assessment
  • Antibody titration
  • Isotype controls
  • Internal controls
  • Spectral overlap
Objectives:
  • Clarify that not all background is equal
  • Clarify how controls should be used
  • Raise awareness about relevant literature
  • Share experiences and different points of view


TUTORIAL 13
Computational tSNE​


Instructors:
Bruce Bagwell, Verity Software House

In this tutorial, a step-by-step explanation of how t-SNE works will be presented. The tutorial will present some of the problems with the original implementation which dramatically limited its potential resolution of cytometry-defined cellular populations. A new variant of the method called Verity Cen-se’ will be presented that is considerably faster than the original method and presents populations in unprecedented high-resolution. Several examples and experiments demonstrating the value of this tool will also be presented.

TUTORIAL 14
Advanced, Open-Source Data Analysis Workflow for Imaging Flow Cytometry
Instructors:
Holger Hennig, Broad Institute
Minh Doan, Broad Institute

Imaging flow cytometry (IFC) enables the high throughput collection of morphological and spatial information from hundreds of thousands of single cells. This high content, information rich image data can in theory resolve important biological differences among complex, often heterogeneous biological samples.

In this tutorial, we demonstrate a pipeline using open-source software that leverages the rich information in digital imagery using machine learning algorithms [1]. Compensated image files (.cif) from an imaging flow cytometer are generated with the software IDEAS from Millipore. The .cif files are imported into the open-source software CellProfiler, where an image processing pipeline identifies cells and subcellular compartments allowing hundreds of morphological features to be measured. This high-dimensional data can then be analyzed with cutting-edge machine learning and clustering approaches using ‘‘user-friendly” platforms such as CellProfiler Analyst. Researchers can train an automated cell classifier to recognize different cell types, cell cycle phases, drug treatment/control conditions, etc., using supervised machine learning. This workflow should enable the scientific community to leverage the full analytical power of IFC-derived data sets.

Outline:
1.Generating image tiles from .cif files and importing the images tiles into CellProfiler
2.CellProfiler pipeline for object segmentation and extraction of hundreds of morphological features per cell
3.Machine learning using CellProfiler Analyst
4.Machine learning using custom scripts (R, python)


TUTORIAL 15
Implementing Best Practices in a Flow Cytometry Shared Resource (Core) Facility


Instructors:
Joanne Lannigan, M.S., School of Medicine Core Facilities, University of Virginia
Monica Delay, M.S., Division of Rheumatology Research Research Flow Cytometry Core, Cincinnati Children's Hospital Medical Center

In November 2016 an ISAC Shared Resource Laboratory (SRL) Task Force published a document outlining a set of “best practices” for SRLs or Core Facilities to use as a general guide for achieving and maintaining standards of excellence in the services they provide. These best practices highlight several important areas that impact the efficiency, quality and reproducibility of services provided by these facilities. The purpose of this tutorial is to provide guidance and generate discussion and feedback on how to best implement these “best practices” across a wide variety and flavors of these SRLs or Cores.

Outline

1.    Introduction of the Best Practices and what is hoped to be achieved through implementation
2.    Brief presentation and background information on each topic including SOPs, Training and Education, Quality Assurance, Laboratory Safety, Data Management, Staffing, and Operations
3.    Identification of potential roadblocks and hurdles and how to overcome them
4.    Benefits of implementation and adherence to these best practices
