Mapping genes on chromosomes
1
Hellow,
I want to map plant genes on the chromosomes. I have gff file. I tried using biomart but it's giving an error.
library(GenomeGraphs)
library(biomaRt)
library(regioneR)
mart <- useMart("plants_mart", host = "plants.ensembl.org")
listDatasets(mart, verbose = FALSE)
mart <- useMart("plants_mart", dataset= "stuberosum_eg_gene", host = "plants.ensembl.org")
useEnsembl(biomart = "mart", dataset = "stuberosum_eg_gene ", host = "plants.ensembl.org", version = NULL, GRCh = NULL, mirror = NULL, verbose = FALSE)
Error in useMart(biomart = biomart, dataset = dataset, host = host, verbose = verbose,
:
Incorrect BioMart name, use the listMarts function to see which BioMart databases are available

mart=useMart("plants_mart", host="plants.ensembl.org","stuberosum_eg_gene")
getBM(attributes=c("ensembl_gene_id","chromosome_name","start_position","end_position", "strand"),
filters = 'ensembl_gene_id',
values = "PGSC0003DMG400029744",
mart = mart)
output:
No encoding supplied: defaulting to UTF-8.
ensembl_gene_id chromosome_name start_position end_position strand
1 PGSC0003DMG400029744 1 81566672 81567534 -1
btw, gtf file is supposed to have chromosome , coordinates and strand information for a feature.
