SUMMARY This Administrative Supplement request aims to collaboratively develop and test open-source, GeoMX data visualization and analysis tools required to support research using this data. Members of the Pregnant Female Reproductive Tissue Mapping Center (TMC) will collaborate with members of the HIVE at Harvard Medical School to fill a current gap in GeoMX visualization tools by working closely to develop a visualization tool for Nanostring GeoMx data based on Vitessce (Aim 1) and to support local visualization and configuration (Aim 2).
