Deleted:differential expression from sc RNA seq

Question

[re_raz]

Hello I hope everyone staying safe and healthy I have question which might be stupid question. This because I am new to bioinformatic and single cell RNA seq analysis. I hope someone help me. The data set consists of 12 samples scRNA-seq and I want to get differential expression to compare between samples. I merged my data, created Seurat Object, and did normalization, scaling and clustering. How I calculate differential expression for my samples?

Thanks a lot
