For a set of target genes that can be mapped to GenBank accession numbers, UniGene ids, IMAGE ids, or Locuslink ids, AnnBuilder processes the source data from LocusLink, Unigene, Gene Ontology Consortium, UCSC Genome Bioinformatics, and KEGG to obtain annotation elements for the target genes and package the annotation data so that they can be accessed in R and used directly by other packages. The help page for each set of annotation data contained by a pacakge has some simple examples on how to access the data. The link "MetaData/Annotation Packages" provides some general information about the sources used and the procedures involved to build an annotation data package using AnnBuilder. A note published in Bioinformatics (Vol. 19, 2003 155 - 156) can be another source of reference except that a database is no longer required by the latest version of AnnBuilder. Let me know if you have more specific questions. > >Looking forward to hear from you. > >Yours Sincerely, >Sunitha Jonnakuty >Ph.D Student >Dept of Molecular Biophysics >German Cancer Research Center ( DKFZ ) >TP3, Im Neuenheimer Feld 580 >D-69120 Heidelberg, Germany > >Ph : ++49 (0)6221 422342 (Office) >Fax : ++49 (0)6221 422333 (Office) Jianhua Zhang Department of Biostatistics Dana-Farber Cancer Institute 44 Binney Street Boston, MA 02115-6084
