  22. Trouble-shooting Ideas • Run from terminal window to see Python error messages. • Use "print" statements. print "Made it to this point." print "myVariable=", myVariable print "value at 25, 25 is", T[25][25] Smart Tools and Procedures

  23. Smart Tool Repository (STR)http://isl715.nws.noaa.gov/STR/index.php3 • Provides an easy to use interface between developers of STs and the users. Promotes sharing of STs so that others can benefit from work done and not duplicate work. • Register tools when downloaded to received bug notification, version updates, and comments on the ST. • Users can also submit bugs and comments to the developer. • Upload a newly developed tool along with documentation and an installation guide. You can even post a ST idea that is in development without submitting the actual code. Smart Tools and Procedures

  24. Smart Tool Repository (STR)Downloading and Adding a Tool • Use the “Site Interface” and choose your region and WFO ID • Choose “Info on Tools” and go to the ST you wish to download • Right click on the “Download Software” and use “Save Link as”. Do the same for the Documentation and Install files if available. • Move the ST to a location where GFE is running and open the ST with an editor such as vi or nedit. Smart Tools and Procedures

  25. Smart Tool Repository (STR)Downloading and Adding a Tool (cont.) • 5) Make the downloaded ST part of the GFE • Use the new ifpServerText program to save the “flat file” into the GFESuite ifpServer. The program takes care of the metadata file needed. • 6) Use the STR to register this tool to receive e-mail notices of bugs and updates. Smart Tools and Procedures

  34. Working with Weather Numeric Weather is a 2-tuple: wxValues -- Numeric Grid of bytes keys -- list of "ugly strings" where the the index of the ugly string corresponds to the byte value in the wxValues grid. Keys = ["Sct:RW:-:<NoVis>:", "Chc:T:-:<NoVis>:", "Chc:SW:-:<NoVis>:" ] Then the wxValues grid is 0 where "Sct:RW:-:<NoVis>:" 1 where "Chc:T:-:<NoVis>:" 2 where "Chc:SW:-:<NoVis>:" Smart Tools and Procedures

  35. Working with Weather Assigning Weather values: getIndex -- given a list of keys, returns the associated index byteValue = self.getIndex("SChc:RW:-:<NoVis>:",keys) byteValue = self.getIndex("Chc:RW:-:<NoVis>:",keys) # Special case for "NoWx" byteValue = self.getIndex("",keys) Smart Tools and Procedures

  40. Smart Script LibraryMissing Data Mode • Set from GFE-->Editing Modes Menu • When there is missing data: • Stop -- stop execution • Skip -- Skips the grid and reports it • Create -- If possible, creates a grid via interpolation. If in the Fcst database, the new grid can be saved. Smart Tools and Procedures
