Please explain your example; it is not at all clear to me.

You say you want the output:
Code:
>gi|546709146|gb|AWWX01426952.1|
acctgctgcatgcgtgcgtggcgtgcaaaatgcagtcaaggcaggtcagtccatgcatgacgtgcaatgcattgcatggcgtgcaaaatgcaggcgtggcgtgcaaaatgcagtcaaaaaattgccgtgcaatgggcc

which seems to have been selected by the line:
Code:
gi|546709146|gb|AWWX01426952.1|	       52962	52984

from the file result.ods which I thought meant that you wanted characters 52962 through 52984 from the data following a line starting with:
Code:
>gi|546709146|gb|AWWX01426952.1|

in the file 1.fasta. But, that string does not appear in 1.fasta and, even if it did, the data from characters 52962 through 52984 would be 23 characters long; not the 138 characters you have said you want to have output.

What am I misunderstanding???

NAME
Bio::SeqFeature::SiRNA::Oligo - Perl object for small inhibitory RNAs. SYNOPSIS
use Bio::SeqFeature::SiRNA::Oligo; my $oligo = Bio::SeqFeature::SiRNA::Oligo-> new( -seq => 'AUGCCGAUUGCAAGUCAGATT', -start => 10, -end => 31, -strand => -1, -primary => 'SiRNA::Oligo', -source_tag => 'Bio::Tools::SiRNA', -tag => { note => 'A note' }, ); # normally two complementary Oligos are combined in an SiRNA::Pair # object $pair->antisense($oligo); DESCRIPTION
Object methods for single SiRNA oligos - inherits Bio::SeqFeature::Generic. Does not include methods for designing SiRNAs - see Bio::Tools::SiRNA for that. SEE ALSO
Bio::Tools::SiRNA, Bio::SeqFeature::SiRNA::Pair. FEEDBACK
Mailing Lists User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated. bioperl-l@bioperl.org - General discussion http://bioperl.org/wiki/Mailing_lists - About the mailing lists Support Please direct usage questions or support issues to the mailing list: bioperl-l@bioperl.org rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

Donald Jackson (donald.jackson@bms.com) APPENDIX
The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _ new Title : new Usage : my $sirna_oligo = Bio::SeqFeature::SiRNA::Oligo->new(); Function : Create a new SiRNA::Oligo object Returns : Bio::Tools::SiRNA object Args : -seq sequence of the RNAi oligo. Should be in RNA alphabet except for the final TT overhang. -start start position -end end position -strand strand -primary primary tag - defaults to 'SiRNA::Oligo' -source source tag -score score value -tag a reference to a tag/value hash -seq_id the display name of the sequence -annotation the AnnotationCollectionI object -location the LocationI object Currently passing arguments in gff_string or gff1_string is not supported. SiRNA::Oligo objects are typically created by a design algorithm such as Bio::Tools::SiRNA seq Title : Seq Usage : my $oligo_sequence = $sirna_oligo->seq(); Purpose : Get/set the sequence of the RNAi oligo Returns : Sequence for the RNAi oligo Args : Sequence of the RNAi oligo (optional) Note : Overloads Bio::SeqFeature::Generic seq method - the oligo and parent sequences are different. Note that all but the last 2 nucleotides are RNA (per Tuschl and colleagues). SiRNA::Pair objects are typically created by a design algorithm such as Bio::Tools::SiRNA. perl v5.14.2 2012-03-02 Bio::SeqFeature::SiRNA::Oligo(3pm)
