  • How to show ALL related sequences in the Tab?
  • It may be difficult to load too many lines in a single page especially for visitors with poor network speed or limited CPU power. So to avoid potential overloading we set to show 100 sequences per page in the information table by default. Users can use the navigation tools on the bottom tool bar of the table to view next or any other page. The auto-paging setting can be turned off by single click the 'Paging off' button on the bottom tool bar of each table (click this button again to re-enable auto-paging).

  • How to make phylogenetic analyses on DRodVir platform?
  • In order to make phylogenetic analyses users MUST perform BLASTN or BLASTP search (see above) first to determine which sequences in the database should be included. In the Tab of BLAST result a 'Phylogeny' button is given at the bottom right. Click the button will bring a pop up window to allow users to select sequences for follow-up phylogenetic analyses (note that the user input sequence for BLAST MUST be included). After user selections just submit the form and an integrated pipeline for multiple sequence alignment and tree construction will be processed in background. Users will have a message window with an ID (8-bit integer). Users can input the ID into the entry at the bottom left of the window and click the button to retrieve the tree later. Both multiple sequence alignment and phylogenetic tree can be saved as local files for further analyses.

  • How to view basic characteristics of the rodents?
  • To bridge the gaps between virologists and zoologists the basic information of rodents such as species, common name, known distribution can be easily browsed when users choose to browse all viruses by rodent (see above), a 'Browse rodents' Tab is present in the right main content panel. Note that to avoid possible overloading of the client web browser, the information is displayed with 25 rodent species per page by default. For quick locating a certain rodent species, users can use the search entry at the bottom toolbar for searching by rodent name/distribution. Click the rodents name in the search results can also bring the Tab with all viruses identified in given species of rodent.

  • How to get the known phylogenetic relationships of the rodents?
  • The phylogenetic relationships between different rodent families were retrieved from a previous study by Meredith et al (Science 2011, 334:521-4) and carefully integrated into the database. Users can click the 'Rodent phylogeny' on the bottom toolbar of the menu panel to open the rodents phylogeny Tab showing the rodent family tree in the main content panel. Or alternatively, when browse the rodents information (see above) users can click the tree icon shown below the rodents' family to show the tree directly with this rodent family underlined. Please note, the rodent family phylogenetic information is also searchable by using the search entry at the bottom toolbar of the rodents phylogeny Tab.

    MISCELLANEOUS

  • How to export the information table as local file?
  • For easy further offline analyses the each information table can be saved as local Excel file using the 'Export table' button at the bottom tool bar of the main content panel. Please note that the saved file contains the same as shown in the current table in web page, so hidden columns or lines been filtered out will not be exported into the Excel file.

  • How to copy the detailed information from the expanded line of the table??
  • Our programs INDEED allow any users to select and copy any part of the detailed information from the table (i.e. after the line is expanded by double click or single click on the leading "+" icon), and it works well in Microsoft IE. However, due to the incompatibility of different web browsers, the select and copy function is known to be disabled by some other browsers including Chrome and Safari. So users are suggested to use Microsoft IE if they want to copy the information. We are sorry for the incontinence.

  • How to easily go back to the Tabs you just visited?
  • The main content panel can contain many different Tab windows. Each information table the users visited is an independent Tab in the content panel, and they won't be lost unless the users close the current web page or the individual Tab in purpose. So the easiest way to go back to the Tabs the users just visited is to click the respective Tab name on the top of the main content. Thus the required Tab will go to the front of all opened Tabs and the contents will not need to be reloaded.
