Description

Six versions of the complete genome for bacteriophage φ X174 as well as a small number of Solexa short reads, qualities associated with those short reads, and counts for the number times those short reads occurred.

Details

The phiX174Phage object is a DNAStringSet containing the following six naturally occurring versions of the bacteriophage φ X174 genome cited in Smith et al.:

Genbank:

The version of the genome from GenBank (NC\_001422.1, GI:9626372).

RF70s:

A preparation of φ X double-stranded replicative form (RF) of DNA by Clyde A. Hutchison III from the late 1970s.

SS78:

A preparation of φ X virion single-stranded DNA from 1978.

Bull:

The sequence of wild-type φ X used by Bull et al.

G'97:

The φ X replicative form (RF) of DNA from Bull et al.

NEB'03:

A φ X replicative form (RF) of DNA from New England BioLabs (NEB).

The srPhiX174 object is a DNAStringSet containing short reads from a Solexa machine.

The quPhiX174 object is a BStringSet containing Solexa quality scores associated with srPhiX174.

The wtPhiX174 object is an integer vector containing counts associated with srPhiX174.
