core_genome() function

[jhcuarta]

Hi

When I run the core_genome command i got the following error

core <- core_genome(mm, type = 'prot', n_cores = 6, method = "accurate") Joining, by = "head" Error in core_genome(mm, type = "prot", n_cores = 6, method = "accurate") : No core_genome found

This is the script I've been running

library(V8) library(pato) library(dplyr) library(tidyr) library(tibble) library(dtplyr) library(foreach) library(doParallel) library(parallel) gff_files <- dir("/home/jason/Documentos/PATO_vibrio/gff_143", pattern = ".gff", full.names = T) gffs <- load_gff_list(gff_files) my_mash <- mash(gffs, type ="prot") species <- classifier(gffs, n_cores = 6, type = 'prot') species %>% group_by(organism_name) %>% summarise(Number = n()) my_mmseq <- mmseqs(gff_files, coverage = 0.8, identity = 0.8, evalue = 1e-6, n_cores = 6, cov_mode = 0, cluster_mode = 0) my_accnet <- accnet(my_mmseq, threshold = 0.8, singles = FALSE) mm <- mmseqs(gffs, type = "prot") core <- core_genome(mm, type = 'prot', n_cores = 6, method = "accurate")

It seems that in your samples it does not find any genes that form a core genome. In other words, there is no common gene in your samples.

What bacteria are you analyzing and how many are they?

Hi 143 Vibrio cholerae genomes, 92 complete, and 51 draft. It seems odd since I've run other pangenome tools
