Error finding variable features in Seurat

Question

[sidrah.maryam]

Hello everyone!

I am trying to find variable genes in Seurat object, however, got this error.

Error in S < FindVariableFeatures(S, selection.method = "vst", nfeatures = 2000) : 
  comparison (3) is possible only for atomic and list types

Can you please explain the possible reason.

Thanks a lot.

Oops, I think I missed a little thing and did blunder. (was stuck on it for long time) Thanks for it, and sorry for such issue. My brain needs a break I guess. Thanks :)
