Signac tutorial counts$Peaks includes extra contigs not in annotation file

[arajeevan]

Hi, I'm trying to do the Signac tutorial with the pbmc_granulocyte_sorted_10k example dataset but I get an error at the step:

create ATAC assay and add it to the object

pbmc[["ATAC"]] <- CreateChromatinAssay(
counts = counts$Peaks,
sep = c(":", "-"),
fragments = fragpath,
annotation = annotation
)

Error in h(simpleError(msg, call)) :
error in evaluating the argument 'x' in selecting a method for function 'genome': unable to find an inherited method for function 'seqinfo' for signature 'x = "ChromatinAssay"'

I looked into it and it looks like there are extra contigs in the counts file that aren't in the annotation file. Maybe since the tutorial was made the pbmc data has been updated to include extra contigs?

Thanks!
