Hi, it seems you're using a fairly old version of scDblFinder, please update to recent versions. It's not just for this package (which improved considerably) but most single-cell related things have evolved quite rapidly in the past year...

Hi @plger, I just installed today using BiocManager::install("scDblFinder"), is there a better way I can install to get the most updated version?

[plger]

So the main problem in your case is that your whole Bioconductor is 3.10, so when you use BiocManager::install you're using all the package versions from last year.
Normally you can always install either the github version (BiocManager::install("plger/scDblFinder")) or the Bioc devel versions (BiocManager::install("scDblFinder", ref="devel")) to get the most up-to-date versions, but the problem is that (in this case at least) the dependencies won't be available to your current Bioconductor.
The new Bioconductor 3.12 will officially be released today, so my suggestion would be to update everything (also install R version 4), and use the latest version.
It might be that the problem you're experiencing can be solved just by loading library(Matrix) explicitly. However, the improvements in scDblFinder since last year are so big that I'd really advice you to update (it's a matter of time before you have to do so anyway!).

Thanks for the recommendations @plger. Sorry for the delayed response. Since I work from singularity images - I had to rebuild the image with the new softwares to support scDblFinder and it took some time to build. I now have R4.0.3 and scDblFinder 1.3.25 and it seems to be working well.

glad to hear!
