Hi, Could you check your input matrix (i.e., in your case, your "data" matrix since you input the logNorm data) to see if there is any invalid value (e.g., NA/INF/NaN)? Also, since http://gerg.gsc.riken.jp/SC2018/ also provides the raw count matrix (UMI.txt.gz), you may also consider using that instead of the Normalized data.
Hi, thank you so much for your response. I did check the data and changed all the NAs to 0 but still encountered the same problem. I tried using the raw count matrix instead to go through the normalization step but I'm getting the following error:
Normalizing layer: counts
Performing log-normalization
0% 10 20 30 40 50 60 70 80 90 100%

Error in `fn()`:

Backtrace:
1. Seurat::NormalizeData(seu1)
2. Seurat:::NormalizeData.Seurat(seu1)
4. SeuratObject (local) `[[<-`(`*tmp*`, assay, value = `<Assay5[,61203]>`)
8. SeuratObject (local) .nextMethod(x = x, i = i, ..., value = value)
9. SeuratObject (local) fn(x = x, i = i, value = value)
I found a solution! I think my meta.data columns did not match up with my counts slot. I created a new object using the following:
stripped.seu <- CreateSeuratObject(counts = scrna1[rownames(seu@meta.data)], meta.data = seu@meta.data)
Hello, I am working with a normalized data set from: http://gerg.gsc.riken.jp/SC2018/. I'm trying to go through the integration introduction vignette. I looked through other issues and saw that the developers have recommended to skip the normalization step when working with already normalized data. So I have skipped this step but while running
FindVariableFeatures()
on my Seurat object, I'm getting the following error:I looked at #2387 and running
DefaultAssay(object = seurat.object)
returns "RNA". This is my session info:
