Strange gene expression map

[Ping-lin14]

Hello,

I performed the analysis based on ArchR: 10x Multiome PBMC, but after reading the visual gene expression, I got a strange map.
Does this mean that in my data, all cells have the same gene expression level?
And I noticed that when I execute the plotEmbedding function, I receive the message No imputeWeights found, returning NULL Does it matter?

Most likely yes. But this should be easy for you to confirm.

I receive the message No imputeWeights found, returning NULL Does it matter?

Only if you want to use imputation
