Thank you very much. This is awesome as well.

I need the gene coordinates (CHR, START, END) for a list of genes. I have the Ensembl IDs, but I have over 200 genes. I have been going to NCBI and Ensembl and entering the Ensembl IDs manually. Is there a software package out there that can do this? Biopython and Pyensembl don't seem to have straight-forward options for this and the websites don't seem to accept lists.
Ex:
Gene ID Ensembl ID CHR Start End
ITGA2B ENSG00000005961 chr17 44372180 44389649
You can query Ensembl from within R using biomaRt:
library(biomaRt)
# the mart, so-to-say the "universe", here H.Sapiens
mymart <- useMart(biomart = "ensembl", dataset = "hsapiens_gene_ensembl")
# list everything that this mart offers
attrs <- listAttributes(mart = mymart)
#/ two example genes:
wanted <- c("ENSG00000066336", "ENSG00000102145")
# retrieve the data for these genes:
genes <- biomaRt::getBM(attributes = c("ensembl_gene_id", "chromosome_name", "start_position", "end_position"),
mart = mymart,
filters = "ensembl_gene_id",
values = wanted)
> genes
ensembl_gene_id chromosome_name start_position end_position
1 ENSG00000066336 11 47354860 47378547
2 ENSG00000102145 X 48786562 48794311
Thank you very much. This is awesome as well.
Using EntrezDirect:
$ esearch -db gene -query "ENSG00000005961" | efetch | grep Annotation | awk -F ":" '{print $2}'
Chromosome 17 NC_000017.11 (44372181..44389649, complement)
