Bio::DB::HTS::Tabix - Object oriented access to the underlying tbx C methods
use feature qw( say ); use Bio::DB::HTS::Tabix; my $tabix = Bio::DB::HTS::Tabix->new( filename => "gerp_plus_plus_31July2014.gz" ); say $tabix->header; my $iter = $tabix->query("1:4000005-4000009"); while ( my $n = $iter->next ) { say $n; }
A high level object oriented interface to the htslib tabix (tbx.h) api. Currently it only supports retrieving regions from a tabixed file, because that's all I needed it for.
filename
The gzipped file you want to query. Must have a filename.tbi (the index is not created automatically)
header
Returns all the header lines as a single scalar from the tabixed file
query
Takes a single region like: '1:4000005-4000009' or '12:5000000' Note: this works exactly the same way as the tabix executable, so '12:5000000' actually means get all results from position 5,000,000 up to the very end of the chromosome. To get results only at position 5,000,000 you should do '12:5000000-5000001'
Returns a Bio::DB::HTS::Tabix::Iterator for the specified region
seqnames
Returns an array ref of chromosomes that are in the indexed file
