The bounds of a sequence location. This is a pair consisting of the lowest and highest sequence offsets covered by the region. The bounds ignore the strand of the sequence location, and the first element of the pair will always be lower than the second.
Sequence position of the end of the location, as described in
List of sequence positions in the location, in order from the 5' end to the 3' end of the location strand.
seqData, extract the nucleotide subsequence for the
location, but any positions in the location lying outside the
bounds of the sequence are returned as
Given a sequence position and a sequence location relative to
the same sequence, compute a new position representing the
original position relative to the subsequence defined by the
location. If the sequence position lies outside of the sequence
Nothing is returned; thus, the offset of the new
position will always be in the range
[0, length l - 1].
Given a sequence location and a sequence position within that
location, compute a new position representing the original
position relative to the outer sequence. If the sequence
position lies outside the location,
Nothing is returned.
This function inverts
posInto when the sequence position lies
within the position is actually within the location.
For an enclosing location and a sublocation in the same
coordinate system, find the image of the sublocation relative to
the enclosing location. For example, if the enclosing location
spans (100, 150) and the sublocation is (110, 120) then
clocInto will be (10, 20).
Returns a sequence location produced by finding the inverse
image of a sublocation, with coordinates given relative to an
enclosing location, in the coordinate system of the enclosing
location. For example, if the enclosing location spans (100,
150) and the sublocation is (10, 20) then
clocOutof will be
Returns a sequence location produced by extending the original
location on each end, based on a pair of (5\' extension, /3'
extension/). The 5' extension is applied to the 5' end of the
location on the location strand; if the location is on the
Minus strand, the 5' end will have a higher offset than the
3' end and this offset will increase by the amount of the 5'
extension. Similarly, the 3' extension is applied to the 3'
end of the location.
True when a sequence offset lies within a sequence
location on the same sequence
True when a sequence position lies within a sequence
location on the same sequence, and occupies the same strand.
True when two sequence locations overlap at any
Contigs that comprise the location
Contiguous sequence locations
Contiguous sequence location defined by a span of sequence positions, lying on a specific strand of the sequence.
Create a sequence location lying between 0-based starting and
ending offsets. When
start < end, the location
be on the forward strand, otherwise it will be on the
reverse complement strand.
Create a sequence location from the sequence position of the start of the location and the length of the position. The strand of the location, and the direction it extends from the starting position, are determined by the strand of the starting position.
Create a sequence location between 0-based starting and ending bounds with a specified strand.
Returns a location resulting from sliding the original location along the sequence by a specified offset. A positive offset will move the location away from the 5' end of the forward stand of the sequence regardless of the strand of the location itself. Thus,
slide (revCompl cloc) off == revCompl (slide cloc off)
