How do I extract feature_info in my rds file?

[Saumya513]

I want to do a trajectory analysis using slingshot on my seurat object. But the function feature_mapper that is created uses feature_info. How do I extract this from my seurat object?

Any help will be appreciated?

Hi @Saumya513,

Thanks for the question! In order to run Slingshot, you will first need to convert your Seurat object into a SingleCellExperiment object using the function as.SingleCellExperiment. There is no way to run Slingshot directly on a Seurat object.

Best, Kelly

Dear Kelly, I tried to run

lineages <- getLineages(data = dimred, clusterLabels = clustering)

I was getting this error:

Error: useNames = NA is defunct. Instead, specify either useNames = TRUE or useNames = FALSE.

I'd appreciate your help.

Thanks and regards, Saumya Gupta

This is probably a result of having a few out-of-date packages installed. You can run BiocManager::install() to update any installed Bioconductor packages and you may also need to update (re-install) the Matrix and matrixStats packages.

Thanks, I'll check it out.
