invalid class “Assay” object issue from Seurat

Question

[QX]

Hi all,

I am running into problem with Seurat when using FindVariableFeatures:

Calculating gene variances
0%   10   20   30   40   50   60   70   80   90   100%
[----|----|----|----|----|----|----|----|----|----|

Calculating feature variances of standardized and clipped values
0%   10   20   30   40   50   60   70   80   90   100%
[----|----|----|----|----|----|----|----|----|----|
**************************************************|
Error in validObject(object = value) : 
  invalid class “Assay” object: slots in class definition but not in object: "assay.orig"

Does anyone run into the same problem? I think it is Seurat problem with its dependencies

If your object was created using older version of Seurat package and you are running the object in the latest version of Seurat package, the error might have originated from that. You can try update your Seurat object if that fixes the issue.

SeuObj <- UpdateSeuratObject(SeuObj)
