Please if anyone has experience with the use of the BSEQ-SC package for the deconvolution of bulk RNA sequencing data with single cell RNA sequencing data I will be very grateful for your suggestion.

I wish to deconvolve my bulk RNA seq data with single cell RNA seq data from the same tissue. I run in to the following error when running the code line below and I do understand the error but not how I can overcome it. Can any one please provide any useful hints?

csfit <- bseqsc_csdiff(ilc_bulk[genes, ] ~ treatment | fibroblast + macrophage, 
                       verbose = 2, nperms = 100, .rng = 12345)

Then comes the error:

Answer from @stupidwolf, @benn, @llrs, converted from comments:

The error complains about the 1686 rownames, while you have 1684 features. I think something is wrong with the naming of your rows.

This may be a bug that you should report to the package maintainer. I cannot really tell without more information about your eset. Looking at this line "Cell type(s): 'fibroblast' (1 total)", is it possible you only have one group under fibroblast? It will not make sense to run a random effect for only 1 group.
