Open the 'ALLSKY' folder, and open the 'allsky.lbl' file. |

Open the 'ALLSKY' folder, and open the
'allsky.lbl' file.

The 'allsky.lbl' file will begin as shown below. Note: If you are using MacOS 9, and the dataset does not open, install lines 3 through 12 below. Do not change other lines, indent or other modifications. You dataset will now open.

The first line, DATASLATE_VERSION_ID = 1.2, is the version of DataSlate at the time this file was written. The latitude and longitude values have not been entered or are not known or not appropriate. By filling the entries with '9's', the lat-lon values have been blocked. Positive Longitude Direction is not applicable in this case. If you know the lat-lon values for the 'lbl' file, they can be entered here. The DATASET NAME refers to the folder in which the datasets reside. This may be seen in the image above. WIDTH and HEIGHT refers to the size of your original image in pixels. Once you have processed a SimpleStruct, all images in the dataset will be based on exactly this dimension and MUST be entered the same way in the 'lbl' file. Most image processing applications will give you the image size in pixels. PIXEL SIZE allows you to 'scale' the 'lbl' entry so that the ruler tool may read in the correct 'scalar' and 'unit' dimensions. The DESCRIPTION FILE allows you to access descriptive or informational text about the dataset by clicking on the Channel One 'Title' window of your dataset. Opening the text file will allow you to edit the file. DESCRIPTION FILE chooses the 'allsky' images at the 'Zoom' level of 4. Examination of other datasets may allow you to see the structure if the 'Zoom' level begins at '1'. ICON selects the thumbnail image for your dataset. If you wanted to change the dataset shown by DataSlate, you would generate your replacement image so that it is exactly 119x110 (width x height). Keep the name of the thumbnail image the same as it is listed on the CD. In this case, 'sky_th.jpg' has a small blue line around the edge and 'sky_un.jpg' does not. Build the two new images in this way. It's best to run DataSlate from your hard drive. If you have loaded DataSlate to your hard drive, you will find a 'dslate' folder with a 'program' folder and an 'iface' folder inside. Open the 'iface' folder and the 'sampler' folder. Name your images 'sky_th.jpg' and 'sky_un.jpg' and overwrite the current images in the folder. Do not change the order of the lines - do not change the indentation or the spacing. Simply change the entries as they appear in the 'lbl' file.
