Exploring SPIAT for HALO image analysis: An R package for the Spatial Image Analysis of Cells in Tissues

Date: 21 November 2022 (US), 22 November 2022 (AEST)
Time: 12:00 – 1:00 pm PST | 3:00 – 4:00 pm EST | 7:00 – 8:00 am AEST
Location: Webinar

Learn how SPIAT can advance your spatial analyses!


In this webinar, Dr. Trigos will present SPIAT, an R tool for the analysis of spatial data that allows rapid analysis with limited setting of thresholds and manual input, as well as a case study in prostate cancer showing the power of identifying spatial patterns to understand the association between the microenvironment, patient genetic background, tumor characteristics, and patient prognosis. 

Dr. Trigos’ team works in the development of algorithms for the characterization, quantification and classification of spatial patterns of cells across spatial proteomics and transcriptomics technologies, borrowing concepts from spatial statistics and ecology.

Learning Objectives

  • Learn how SPIAT can be applied to HALO data 
  • Understand how cell co-localization can be measured with SPIAT  
  • Learn the importance of choosing spatial metrics based on specific research questions 
  • Explore a case study of spatial analysis that links spatial patterns of the microenvironment with tumor genetics
