Each sample contains a compressed gzip file with one or more sequencing files in fastq format.
In the 5' RACE samples these files contain the sequencing of TAP-treated (TAP+) and not-treated (TAP-) combined.
The sequencing reads can be sorted to the TAP+ or TAP- sub-samples by a sequence of a tag in the 5'-end of the read.
The whole-transcriptome samples do not contain tags.
