[galaxy-user] fetch sequence functionality

Hi, I uploaded a tab-delimited file(this was constructed within R using write.table) into Galaxy with chr, start, end, and esembl_TSS_name. Whilst I am able to use fetch sequence function, currently not able to include the Esembl ID in the FASTA output. I am able to include the Ensembl name in the interval format but not in FASTA format. thanks, Lawrence
