Usage

Using the NAWS Client

  1. Please download the appropriate naws-client archive for the appropriate system (Windows/Linux)

  2. Unzip the archive and place it in the html directory of the web server. On Windows machines the html directory is located at Apache_Installation_Directory\Apache Group\htdocs. On Linux/Unix machines, for new versions of Apache (2.x or higher) this is located at /var/www/html and for older ones (1.3.x) at Apache_Installation_Directory/htdocs

  3. Place the nusoap.php file in the same directory as that of the NAWS client

  4. Please create an uploads directory in which all the data files and output zip archives of the analyses will be stored. By default the uploads directory is located in the directory of the NAWS client.
    NOTE: For Linux systems do a chmod 755 on the uploads directory folder.

  5. Start the apache webserver. The NAWS client can be accessed at http://localhost/naws-client/phpClient.html. To access the client remotely please replace localhost with IP or the hostname of the machine.

  6. There are 2 options: (a) Run a fresh analysis. (b) View the list of analysis run in the past. Since this is the first time the client has been installed please select option (a).

  7. Please select a comma or tab delimited text file containing the 2D data matrix. A sample data file can be found here.

  8. Please select an appropriate analysis type and set the parameters of that analysis.

  9. Then select an appropriate preprocessing type desired on the input data matrix

  10. Finally enter the Username and Password for authentication to the NAWS server engine and then hit Run.

  11. Please wait while the analysis is being executed at the server. The results will be automatically retrieved by the NAWS client as soon as they are available.

  12. If option (b) is selected then only the Username and password need to be entered for authentication to the NAWS server engine. The system will return a list of analyses invoked by this particular user in the past.

  13. There is an option either to delete the log about a previously run analysis or to retrieve the results for a previously invoked analysis run. Note that the status column indicates if the analysis completed successfully. A value of 0 indicates analysis is still executing, 1 indicates successful completion of an analysis run whiile 2 indicates that an error occured during the analysis invocation.
