Unable to install new version of DropletUtils

[liron27]

Hi,
I have tried to install the new version of the package using:
devtools::install_github("MarioniLab/DropletUtils")

and got the following error:

ERROR: compilation failed for package ‘DropletUtils’

• removing ‘/tmp/Rtmp4VjwFR/Rinst19fd655306c7/DropletUtils’

Thanks

Try installing using the recommended instructions on the Bioconductor landing page.

I did but it doesn't include the new function removeAmbience

You can either wait a few hours for the new builds to propagate on Bioconductor. Or you can give me much more detail about the entire error log, I can't figure out what's going on from just the last line.

I just copied the removeAmbience function from github to my local directory and then I used the following code:

raw.count <- Read10X(data.dir = "path.to.raw.count")
ambient <- estimateAmbience(raw.count)
x<-removeAmbience(raw.count,ambient, colnames(raw.count))

I am not sure if this is the way to go, but it is still running (for almost 20 minutes now...)

Stop, stop stop. Hold up. You really need to give it clusters. Did you read the documentation?

Install the package properly rather than doing whatever you're doing.

[liron27]

I read, but have few issues: 1. Doing the clustering on the original raw data (without cleaning ambient rna) is computationally heavy - my original raw data has over 6 millions barcodes ... 2. Should I run the entire pipeline of normalization, PCA, clustering on the raw data and then bring it back to “removeAmbience”? Thanks!

I doubt you have 6 million cells generated from a single run of a 10X machine. The maximum number of barcodes is around 700k, at least for versions 2 and 3 of the 10X chemistry.

[liron27]

Yep, I suspected it’s an issue... I am using the “Read10X” function with a path to the directory that contains the barcodes, features and matrix.

The book build crashed so you won't be able to see the latest chapter of the book, but you can just read it from the Rmarkdown starting at:

https://github.com/Bioconductor/OrchestratingSingleCellAnalysis/blob/092880538f4c475fd397c6ab390a69027c545cdc/droplet-processing.Rmd#L137

Or you can just wait for Friday, hopefully the book will have built by then.

Thank you!

Regarding the 6 million barcode issues from 10x - 10x increased the barcode # in the whitelist in V3 version to roughly ~3.5 Million BCs. I believe the barcodes.tsv.gz contains barcode sequences and their reverse complement sequences, so making the total # ~6.8M.

I would be shocked if all 6 million barcodes had counts. Even looking at the existing output that I get from CellRanger 3, I only get non-zero counts for ~600k barcodes.

[liron27]

This is from 10x genomics I’m using the makecount command to generate both the unfiltered and filtered matrix from the fastq file.

Did you resolve your issue?

No
