rule all:
    input: targets

rule get_fq:
    input: lambda wildcards: FTP.remote(f"ftp.sra.ebi.ac.uk/vol1/fastq/{wildcards.accession[:6]}/{wildcards.accession}/{wildcards.accession}.fastq.gz", static=True, keep_local=True, immediate_close=True)     output: os.path.join(data_dir,"{accession}.fq.gz")
    shell: "mv {input} {output}"

Can also use HTTP.RemoteProvider(), same link. Potentially faster?
