Estimation of Copy Number of alterations(CNA) in Sc-RNA Seq data

Hi All,

I'm working on single-cell RNA seq data mostly with the Seurat package and SCE object. I need to estimate Copy number alterations/aberrations (CNAs) for my data but I could not find that many tools for this purpose.

Any recommendation tools in R (preferably applicable of Seurat object or Sce object) for the estimation of CNAs would be appreciated. Thanks. Maria

There are several tools for this. inferCNV and CONICSmat are two that are fairly easy to use and that I've seen cited a few times. It's easy to run both from SCE or Seurat objects.

@jared.andrews07, Thank you, I was trying to use inferCNV on my Seurat object. but inferCNV requires 4 different files which I was not able to implement. I just could extract the count file from my Seurat object. I annotated my raw data and have symbols and gene names and chromosome positions in my Seurat object. also, I annotated cell types with SingleR library and have a cell types column in my object.

Okay, well, all of those inputs are pretty straightforward, so I'm not sure what exactly you're having issues with without you telling us.
