5.4 Saving and Retrieving Lane Images

Some applications may need or prefer to save lane images in addition to or in place of the full image. A good example would be to do a visual comparison of a saved lane from one image with a lane or several lanes of another image or several lanes from different images. While the default is NOT to save lane images, they may saved by setting a toggle in the Options Submenu. The lane image may later be recalled for display via the Image Submenu. However, only the lane image data are saved; band detection marks within a lane are not saved with the lane image. For a given image, if the toggle to save lanes is enabled, all lane images are saved; if individual lane images are to be deleted, you will have to eliminate them from the UNIX file system independent of DNA/GUI. Here's the process to save lane images:

• From the Commands Menu, click [Options] .

• From the Options Submenu, click [Lane Save] . Two messages are posted to the Status Information Region:
  
  "Saving Lane Images enabled."
  "Save Lane Profiles enabled." (ignore)

• In the Options Submenu, click [Done] .

• From the Commands Menu, click [Operations .

• From the Operations Submenu, click [Save Results] . Assuming an image is displayed and has been analyzed at least through delineating lane boundaries, any interim results are saved in the import file ( section 3.8). In addition, individual lane images are saved. They are saved as import files, one file per lane, with the image data embedded with the import information. For example, image names for lane 8 would be:
  
  k102.avg.imp.ln8.imp (pre-normalized),
  k102.avg.w.imp.ln8.w.imp (normalized).

  And to recall a lane image:

• From the Commands Menu, click [Image] .

• From the Image Submenu, click [Open Extra] . The Image File Browser appears; click over the name of a lane image. The outline of the lane image will extend from the location of the pointer; move the pointer to where you would like the image placed; click MB1. The image will be displayed at that point.

• Other lane images may be displayed; again, click [Open Extra] .

  Note: When the primary image is closed, the toggle to save lane images is disabled (no lane save) and must be reset after each primary image is opened.
