Error in apply(rownorm, 2, max) : dim(X) must have a positive length

Hi,

I am using my own seurat objects and when I run getMetaPrograms I get this error:

geneNMF.metaprograms_1k <- getMetaPrograms(geneNMF.programs_1k,
+                                         metric = "cosine",
+                                         weight.explained = 0.5,
+                                         nMP=10)
Error in apply(rownorm, 2, max) : dim(X) must have a positive length

When I try with the test data it works and I can't identify what the differences are between my object and that of the test. Any help would be great

Hello,
any chance you could send your seurat object, so I can try to reproduce the error?
