| Class | Bio::Sim4::Report::SegmentPair |
| In: |
lib/bio/appl/sim4/report.rb
|
| Parent: | Object |
Sequence segment pair of the sim4 result. Similar to Bio::Blast::Report::HSP but lacks many methods. For mRNA-genome mapping programs, unlike other homology search programs, the class is used not only for exons but also for introns. (Note that intron data would not be available according to run-time options of the program.)
| direction | [R] | Returns directions of mapping. Maybe one of "->", "<-" or "" or nil. This would be a Bio::Sim4 specific method. |
| midline | [R] | Returns the "midline" of the segment pair. Returns nil if no alignment data are available. |
| percent_identity | [R] | Returns percent identity of the segment pair. |
| seq1 | [R] | Returns segment informations of ‘seq1’. Returns a Bio::Sim4::Report::Segment object. These would be Bio::Sim4 specific methods. |
| seq2 | [R] | Returns segment informations of ‘seq2’. Returns a Bio::Sim4::Report::Segment object. These would be Bio::Sim4 specific methods. |
Creates a new SegmentPair object. It is designed to be called internally from Bio::Sim4::Report::Hit object. Users shall not use it directly.
