ERROR Found in .fastTSSCounts for creating arrowfile

[macrophage666]

Hi,

I have trouble creating an arrowfile. I have non-standard chromosomes for our fragment files, so I customized the geneAnnotation and genomeAnnotation which have the same seqnames with our fragment files but I still got this error. Here is log: ArchR-createArrows-2d96605e219c6f-Date-2024-03-04_Time-14-05-54.045259.log

Thanks

Hi @macrophage666! Thanks for using ArchR! Lately, it has been very challenging for me to keep up with maintenance of this package and all of my other responsibilities as a PI. I have not been responding to issue posts and I have not been pushing updates to the software. We are actively searching to hire a computational biologist to continue to develop and maintain ArchR and related tools. If you know someone who might be a good fit, please let us know! In the meantime, your issue will likely go without a reply. Most issues with ArchR right not relate to compatibility. Try reverting to R 4.1 and Bioconductor 3.15. Newer versions of Seurat and Matrix also are causing issues. Sorry for not being able to provide active support for this package at this time.

have you solved it? I met the same error

have you solved it? I met the same error Yes, I solved it. Did you also use a non-standard chromosome? If so, this error could be caused by that. The best way to solve it is to customize your BSgenome and Txdb packages first, using the same fa and gtf files you used to get your fragment files. Then, when creating genome annotation, exclude the unknown chromosomes. Remember to keep chrPrefix as false before creating arrowfiles.

Here are some tutorials for helping you forge your customized BSgenome and Txdb package: https://bioconductor.org/packages/release/bioc/html/BSgenomeForge.html https://bioconductor.org/packages/release/bioc/vignettes/GenomicFeatures/inst/doc/GenomicFeatures.html

It might take some time to get those two packages ready, but there is a high chance that your problems will be solved by doing so. I would like to help if you meet other problems in this process.
