Table 4.

The dictionary and parse sizes for prefixes of a database of Salmonella genomes, with three settings of the parameters w and p

Number of genomes	Size	$w=6,p=20$			$w=8,p=50$			$w=10,p=100$
		Dict.	Parse	%	Dict.	Parse	%	Dict.	Parse	%
50	249	68	43	44	77	20	39	91	10	40
100	485	83	85	35	99	39	28	122	19	29
500	2436	273	424	29	314	194	21	377	96	19
1000	4861	475	847	27	541	388	19	643	192	17
5000	24936	2663	4334	28	2915	1987	20	3196	985	17
10,000	49420	4190	8611	26	4652	3939	17	5176	1955	14

Again, all sizes are reported in megabytes; percentages are the sums of the sizes of the dictionaries and parses, divided by the sizes of the uncompressed files

For each prefix, the sizes are in italics for the settings with the best overall compression
