Compartments phasing error

[ABignaud]

Hi,

Trying to do some compartments on a bacterial chromosome (fasta file with only one sequence), I got the following error message. If I am not doing the phasing, the function works.

library(HiCExperiment)
library(HiContacts)
library(Biostrings)
library(BSgenome)

# Import
cf <- "B_caecimuris_v2_MM81.mcool"
res <- 16000
hic <- HiCExperiment::import(CoolFile(cf), resolution = res)
phasing_track <- readDNAStringSet("B_caecimuris_v2.fa", format = "fasta")

# Comp
hic <- autocorrelate(hic)
compts <- getCompartments(hic, genome=phasing_track)

Thanks for your help !!

I got the same error for multichromosomic reference.

Can you check the names of your fasta files (names(genome))? The only instance in which I can replicate your results is when I use a fastq file with spaces in the chromosome names.

[ABignaud]

I just look, i don't have any space in that genome names, just one sequence called:
>B_caecimuris

Thanks for checking. I'll investigate more
