phiX174Phage {Biostrings} | R Documentation |
Six versions of the complete genome for bacteriophage \phi
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.
The phiX174Phage
object is a DNAStringSet
containing the
following six naturally occurring versions of the bacteriophage \phi
X174
genome cited in Smith et al.:
The version of the genome from GenBank (NC\_001422.1, GI:9626372).
A preparation of \phi
X double-stranded replicative form (RF) of DNA
by Clyde A. Hutchison III from the late 1970s.
A preparation of \phi
X virion single-stranded DNA from 1978.
The sequence of wild-type \phi
X used by Bull et al.
The \phi
X replicative form (RF) of DNA from Bull et al.
A \phi
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
.
