We have made a few revisions to the CTPP Access Tool (CAT) software (including adding a new feature or two) which we think will benefit you. To take advantage of the changes you need to uninstall the version of the software provided with the Part 1 CDs and then install the new version from the Part 2 CD.
To uninstall the old software, click on the Windows Start menu and choose Settings, Control Panel, and Add/Remove Programs. Click on the CTPP Data Browser to highlight it and then click the Change/Remove button. If you are asked about removing shared files it is safest to click on the "No to All" button. Although you will receive a message that says some elements could not be removed, we have found that this is not a problem and you do not need to remove anything else. This completes the uninstall procedure.
To reinstall the software, use the CD-ROM sent to you for Part 2. Install the software as you did in Part 1 from the Flash start-up screen. Follow the prompts in the install shield program. You will need to reboot your computer once the installation is complete.
Data from Part 1 and Part 2 cannot be mixed, i.e. you are not allowed to include data from Part 1 and Part 2 in the same session. Therefore, once you have reinstalled the software, it is advisable to create a different directory for your Part 2 sessions. This is not a required step, but it will make it easier for you to distinguish between sessions. Please note that sessions already created from Part 1 will still work with this new version of the software.
Once you start the software, you will see new radio buttons for Parts 1, 2, and 3 at the top of the CTPP Session Manager window. Click the button for whichever part contains the data you want to work with in that session. Note that if you click the Part 2 radio button but then select Part 1 data, the software will not know this is inconsistent or stop you from doing it. The software will not, however, allow you to later add Part 2 data to a session that has Part 1 data in it or vice versa. It is up to you to keep the session names and locations consistent with the data contained within them.
During the process of selecting geographic areas on the Create Session screen, you will see a counter at the bottom left of the window just below the list of geography. This is one of the new features. The counter tells you how many geographic units exist for that particular summary level for the entire state. It will also tell you how many you have selected for the session. For geography below the place level there may be some "residual workplace categories" showing up in the file. (See the file Residuals.doc for information about residual workplace categories.) When residuals are present for a summary level there will be a second counter for the residuals displayed below the first one.
If you want to see the counters for your existing Part 1 sessions, replace the contents of the Geofiles folder, found within the Shapes folder, for the state(s) with which you are working. For example if you are working with Virginia, replace C:\VA\Shapes\Geofiles from Part 1 with the same folder off your new Part 2 CD-Rom. This will also let you see the "No data" message in the geography list to indicate where BG and TAZ data are not available, another new feature in this version of the software.
