[galaxy-user] embl 66 genome for RNAseq analysis

Hi, How do I run Tophat and RNA-Seq analysis using the GRCH37- embl 66 genome? I noticed there is no input for this genome version. Can I construct a reference genome from the following embl format source sequences: ftp://ftp.ensembl.org/pub/release-66/embl/homo_sapiens/, and map it against my RNAseq data?
