DEGs of Clusters

Hello guys! I am a student who recently got into bioinformatics and doing a small project! I am trying to do DEGs of >4 clusters and rank genes by logFC and perform GSEA with Hallmark pathways but I am not sure where to start. If there are any good resources or advice, I would really appreciate it! Thank you!

How to lower the numbers of clusters and find the best parameters (Spatial Transcriptomics)

Hi bioinformatics experts!

I am doing a project but i am struggling with finding parameters to lower the numbers of clusters. I am trying different parameters such as lowering resolution, lambda, and k_geom.

I tried a total of three so far and they all look similar so I decided to make this post to get some ideas of how i can lower the numbers of clusters and make it clear.

Trial1: K_geom 30 and resolution = 0.5
Trial 2: K_geom 30 and resolution = 0.1

Trial3: K_geom10 and resolution = 0.5

Parameters I was told to adjust:

Before running BANKSY, there are two important model parameters that users should consider:

  • k_geom : Local neighborhood size. Larger values will yield larger domains
  • lambda : Influence of the neighborhood. Larger values yield more spatially coherent domains

I ended up having 44 clusters and I would love to get some insights!

Thank you!
