Hi folks:

I am trying to get raw RNASeq data from ENA and wonder how to know the length of the sequences in those FASTQ files without downloading them?

In the query design I follow their [guide][1], and use the "`nominal_length>XXX"` in the query, but this filtering mechanism doesn't work...

Thanks!

Get the count of total bases and number of reads from ENA, and do below calculation,

    Read length = Total Bases/ number of reads
