[galaxy-dev] Galaxy Url for Fasta and Bed index files

Hello, What is an appropriate galaxy URL to use to obtain bed and fasta index files? I have tried below: myGalaxy.org:port/dataset/get_metadata_file?hda_id=[fasta_dataset_id]&metadata_name=fasta.fai {for fasta index} and myGalaxy.org:port/dataset/get_metadata_file?hda_id=[bed_dataset_id]&metadata_name=bed.idx {for bed index} While looking through metadata for both bed and fasta file at: myGalaxy.org:port/api/histories/[history_id]/contents/[api_id] I realized that it lacks a meta_files list. Is there a way to populate this list for bed and fasta files as well? Example: For bam files this list populates as bam_index and hence I use metadata_name=bam_index and an appropriate bai file downloads. Thank you Asma
