I tried to download the library ERX5671923 from SRA using fastq-dump with the --split-files option. It is a library from the Fly Cell Atlas (experiment ERP129698 in SRA). I retrieved only one file per run (e.g ERR6032593). As it is a paired end 10X V3 library I was expecting to retrieve 2 or 3 files (Read 1, Read 2 and potentially Index 1) but it contains only one single file with 91bp reads. Do you have any idea if it is possible to use this file and, if yes, how to use it? I want to generate abundance matrix using kallisto/bustools.
