Table 1. Read counts and mapping information.

Sample	FASTQ count (Longest read: Average length)	Mapped to RSV (Longest mapped read)	Mapped to Human Transcripts (Longest mapped read)
MRC-5 mock	2,195,978 (16,860: 1358.5)	0	1,945,497 (16,859)
MRC-5 6hpi	1,577,904 (22,167: 1426.4)	3192 (8,015)	1,328,890 (22,166)
MRC-5 16hpi	2,380,322 (19,372: 1367.1)	76,702 (9,880)	1,992,491 (19,371)
MRC-5 24hpi	1,585,580 (12,629: 1145.4)	147,323 (7,196)	1,125,920 (12,628)

Table to show total number of reads, longest read and average read length for each dataset alongside mapping data for reads mapping to human transcripts or the RSV genome. For the FASTQ data we also indicate the longest read length and average read length. For the mapped data we also indicate the length of the longest read mapped.
