Bio.Net Demo User Manual
Bio.Net demo runs under Windows 2000/XP. Recommended hardware: 512 MB RAM or larger, high speed Internet connection.

(1) Downloading new data
.  Click "Demo 1" tab on the top of the software window, as show below. Click a "Go..." button to download data from a remote database. After downloading, the software will automatically re-format the data in to XML format and store them at the the local computer. (The upstream sequences and homologous gene information are not stored in XML. This will be changed in later versions.)  The paths of newly generated files will be shown in the text bar below the "Go..." button.

(2) Building local database and detecting inconsistencies among databases. The newly download data have not yet been integrated with other data from other databases. To integrate them, click The "Demo 2" tab. Choose the appropriate "Go..." button to re-integrate one of the three local databases: human gene database, mouse gene database and rat gene database. If inconsistent information from different databases is found while integrating databases, such information will be saved into a .log file. A warning message will show up and indicate where the .log file is stored. Users can browse these .log file with a text editor. 

(3) Batch information retrieval. To retrieve all information from the integrated databases, click The "Demo 3" tab.  Click the "Load Gene List (LocusLink IDs)" button, and indicate a file containing LocusLink IDs. The LocusLink IDs will show at the left pane of the software window. Click on a LocusLink ID, all related information to this gene will show up in right pane. In the right pane, click the tabs: General information, Sequence information, Protein information, Gene Ontology, and PubMed to view related information. Click the "Save Gene Annotation Information" button to save the retrieved information to a file.

Choose a LocusLink ID, and click on the PubMed tab to view all PubMed papers that are linked to this gene. Click on the PubMed ID to view more information.

 

Choose a LocusLink ID, and click on the "HomoloGene" tab. All the homologous genes, in totally 16 possible species,  will be listed, together with evidence and sequence identity information.

(4) Retrieving upstream sequences. Click "Demo 4" tab. UCSC Genome Bioinformatics has compiled a collection of sequences 5000 bases upstream of annotated transcription start of RefSeq genes for human, mouse and rat. The upstream sequence retrieval tool queries this upstream sequence collection. Providing a list of RefSeq IDs, users can choose to retrieve any lengths, up to 5000, of upstream sequences. Please provide the path for an input file in the text bar at the top. The input file should contain a column of RefSeq ids, like this:
    NM_000014
    NM_000015
    NM_000016
    NM_000017
    NM_000018
Please indicate the appropriate species. Please indicate the length of upstream sequences to retrieve. Put the path of the output file in the text bar at the bottom. Click the "Retrieve!" button at the top to start retrieving. A message box will pop up after the retrieval.

(5) Retrieving homologous genes. Click "Demo 5" tab. In the input file, please provide a list of LocusLink IDs of human, mouse or rat genes. At the middle of this page, check or uncheck the target species in which the user want to retrieve homologous genes. Click the "Retrieve!" button at the top. The demo application will find their homologous genes in altogether 15 species*, if applicable, from the HomoloGene database. The following information will be stored at the user indicated output file: LocusLink id from the original user input file, the LocusLink ID of the first homologous gene, the species of the first homologous gene, the percent similarity between the original gene and the first homologous gene, the type of the similarity# between the two genes, information about the 2nd, 3rd, ..., homologous genes.

* All the species included in the HomoloGene database: Arabidopsis thaliana, Bos taurus, Caenorhabditis elegans, Danio rerio, Drosophila melanogaster, Homo sapiens, Hordeum vulgare, Lycopersicon esculentum, Medicago truncatula, Mus musculus, Oryza sativa, Rattus norvegicus, Sus scrofa, Triticum aestivum, Xenopus laevis, Zea mays.

 # The types of similarity are: reciprocal best among 3 or more organisms, reciprocal best match between 2 organisms, curated homology relationship.

After pressing the "Retrieve!" button, information about the user requested homologous genes will be output into the user indicated output file. Furthermore, a XML file containing the same information will be generated. The names and directories of the output files will be reported by a dialog box, such as:
