loom file for rna velocity

hi all, i'm trying to do a rna velocity analysis on a seurat object. I saw that loom files with spliced ​​and unspliced ​​transcripts are required, but, assuming that I only have the seurat object as input, how do I produce the loom files?

rnavelocity scrnaseq seurat loom

You need to run RNA velocity CLI seperatly for your samples.

Link for the Tutorial

Then you can convert Seurat R object to loom file using SeuratDisk

OR

You can open velocyto loom files in R and do the downstream.

Hi, I don't have the bam files. The Lab I'm working for just gave me the SeuratObject. So, if I understood, I cannot do the analysis with only the object, I need the bam files of my samples to generate loom files, is it correct?

For velocity estimation, you need spliced and unspliced count and yes in this case you need bam files.
