Issue with labelling of reference scRNA-seq data #24
Comments
Thank you for your interest in our tool.
We currently recommend users to use clustering methods developed for
scRNA-seq dataset, and annotate each biologically meaningful cluster.
Usually for tumor cells, we recommend refining it to subtypes (cell
states). We are planning to work on this problem in hope of providing a
statistically principled way to address this in the next version of
BaysePrism.
Best,
Tinyi

Hello,
there are some guidelines in the tutorial to annotate the reference
scRNA-seq data, for example:
- "Define cell types as the cluster of cells having a sufficient
number of significantly differentially expressed genes than other cell
types, e.g., greater than 50 or even 100"
- "Define multiple cell states for cell types of significant
heterogeneity, such as malignant cells, and of interest to deconvolve their
transcription."
But I could not find any suggested workflow to annotate the reference data.
What would be the ideal way to generate the cell label and cell state
annotations? Are there any suggested tools I could use?
Thank you and best regards

Thank you for you quick reply! So a reasonable workflow could look like this: Is that correct? Thanks again and best regards |
We don’t usually cluster on umaps. Usually i do on the PC space.
You can subset cell types you believe to have high heterogeneity, e.g.
tumor cells, and recluster them to get finer clusters to use a cell states.
For details you may refer to tutorials of scanpy or Seurat.

So a reasonable workflow could look like this:
UMAP -> cluster -> annotate cell types -> cluster cell types with high
quantity of cells -> annotate cell states
Is that correct?
Thanks again and best regards
