1. BioC2023 Package Demo Analyzing Spatially-Resolved Transcriptomics Data from Visium using spatialLIBD Louise Huuki-Myers Leonardo Collado Torres Staff Scientist Investigator @lahuuki lahuuki.github.io Download these slides: speakerdeck.com/lcolladotor lcolladotor.github.io @lcolladotor August 2, 2023
2. Goals for this package demo 1. Access Data from the spatialLIBD 2. Understand the SpatialExperiment data structure 3. Visualize continuous and discrete variables in spatial Data 4. Gene set enrichment analysis 5. Use spatialLIBD registration tools for marker finding 6. Complete spatial registration on an example data set Slides:
