Velocyto- Seurat - invalid class “LogMap” object: Duplicate rownames not allowed
Ruba-Mahmoud opened this issue · 5 comments
Hello, first thank you for developing such great tools
I am Ruba PhD student in Germany and I am doing scRNAseq analysis for my data, I wanted to check the velocity and so I generated the loom files by velacyto, I wanted to continue with Seurat with .r but unfortunately am facing some errors, I looked many published errors, tried to downgrade the Matrix Package (where Seurat didn't work anymore) I had to upgrade it again, the error am facing is | | 0%Error in validObject(.Object) :
invalid class “LogMap” object: Duplicate rownames not allowed
taking into account there's no duplicated rownames could somebody kindly look into it and give an advice if something could be done so I can go through the velocity analysis in the end.
thank you in advance
Kind regards!

Hi, please check for duplicate column names in the infercnv object's expression and the counts matrix. If you do, then getting rid of them will help. I was running CNV analysis and had to remove duplicate column names to get rid of the error.
Hi. I got the same error, have you solved yet?
Also hoping for a solution.
in the infercnv object's expression
@fariznazir Can you clarify what you mean? The person who originally made this issue does not have an object called infercnv. The error refers to rownames. Is invercnv part of the loom file? are colnames converted to rownames at some point?
