Bio::DB::GenBank can be used to retrieve entries corresponding to these ids but bear in mind that these are not Genbank entries, strictly speaking. Some features of bioperl that require modules from bioperl's auxiliary code repositories. Some of the manipulations possible with SimpleAlign include: slice(): Obtaining an alignment "slice", that is, a subalignment inclusive of specified start and end columns. To explicitly access sequence data from a local relational database requires installing and setting up the modules in the bioperl-db library and the BioSQL schema, see "IV.3" for more information. The Bio::Perl module provides some simple access functions, for example, this script will retrieve a swissprot sequence and write it out in fasta format. A Location object is designed to be associated with a Sequence Feature object in order to show where the feature is on a longer sequence. have an advice for you If you are totally beginner and you just want to learn any programming. Automated searching for putative genes, coding sequences, sequence-tagged-sites (STS's) and other functional units in genomic and expressed sequence tag (EST) data has become very important as the available quantity of sequence data has rapidly increased. Typical syntax is shown below. Finally, there's a HOWTO on features and annotations (http://bioperl.org/HOWTOs/html/Feature-Annotation.html) and there's a section on features in the FAQ (http://bioperl.org/Core/Latest/faq.html#5). More details on bioperl-db can be found in the bioperl-db CVS directory at http://cvs.bioperl.org/cgi-bin/viewcvs/viewcvs.cgi/bioperl-db/?cvsroot=bioperl. Bioperl offers several perl objects to facilitate sequence alignment: pSW, Clustalw.pm, TCoffee.pm and the bl2seq option of StandAloneBlast. This has significant efficiency advantages but means that pSW will not work unless you have compiled the bioperl-ext auxiliary library. For more information on the Bioperl Pise interface see http://www-alt.pasteur.fr/~letondal/Pise/ or the documentation in the bioperl-run package. Alternately, bioperl permits indexing local sequence data files by means of the Bio::Index or Bio::DB::Fasta objects. Typical syntax looks like: Further information can be found at Bio::Tools::GFF. SeqIO can also parse tracefiles in alf, ztr, abi, ctf, and ctr format Once the sequence data has been read in with SeqIO, it is available to bioperl in the form of Seq, PrimarySeq, or RichSeq objects, depending on what the sequence source is. For more discussion of design and development issues please see the biodesign.pod file in the package or biodesign.html (http://bioperl.org/Core/Latest/biodesign.html). The retrieval of NCBI RefSeqs sequences is supported through a special module called Bio::DB::RefSeq which actually queries an EBI server.
