is it normal to have zero mitochondria genes counts in my 10X data which is from Cellranger 5.0 count?

Question

[FantasticAI]

I'm trying to perform QC on my scRNAseq data which is from 10X, I find out there is zero mitochondria genes in my data, is this normal. I used the following code:

PercentageFeatureSet(data1101, pattern = "^mt-")

or

PercentageFeatureSet(data1101, pattern = "^MT-")

Both show zero.

What organism is it, what reference genome are you using, what kit was used, and was it single nucleus RNA-seq?

Thank you for the comment, I just checked the data source, and they are single nucleus RNA seq, that is why they don't have any mitochondria genes

It's great when the answer ends up being so simple. Thanks for following up!
