Differential expression (like in your paper)

[Magisterh1]

Hi!

I really like your tool! I need to calculate differential expression between certain spots like you did in Figure 6c / 6d of your paper "Estimation of cell lineages in tumors from spatial transcriptomics data". Can you provide me with some code how to select/group spots and how to perform the DE?

Thank you!!

Hi, @Magisterh1 ,

Thank you for your interest in SpaCET.

Per your request, I developed a new functionality in our package. You can open up an interactive visualization panel by setting interactive=TRUE to browse all your results. Particularly, you can select and download the spots of interest.

SpaCET.visualize.spatialFeature(SpaCET_obj,interactive=TRUE)

After getting two groups of spots, you can use the shared code in the following link to perform DEA and GSEA.

Please let me know if you have any further questions.

Best,
