Hi Ji-Hye,
Are you filtering cells with low counts (e.g. less than 200 or 500)? My suspicion is that those cells causing the problem may have overall low cell counts and you can avoid the issue by filtering cells with low counts first. And are you using the default of 2000 overdispersed genes? You could maybe try 3000 but I wouldn't go much higher than that because eventually it introduces a lot of noise when you normalize genes to uniform variance.
I'll consider printing a full list of the offending cells in the future.

Yes, I proceeded with the analysis using only the final remaining cells after removing those with fewer than 200 counts, and completing all additional processing and annotation steps.
I utilized the default of 2000 variable genes, as suggested, cells with counts between 200 and 500 might have been problematic.
Even when attempting with 3000 genes, I encountered the same error with 12 cells.
Fortunately, after removing only the 4 cells detected in the message from the results of the analysis performed with 2000 genes and rerunning it, it proceeded smoothly.
Thank you for the prompt response and assistance!

Hi, I encountered the same errors! I would like to know if adjusting the number of variable genes would affect the results?Thanks!
