Select Pair of 2D Gel Images to Flicker Compare from cached 2DWG or your URLs


You may Flicker compare any two of the images found in any of the following two sources. Although this database methodology was designed for 2D protein gels, it can easily be applied to other image domains.

Image sources: These two sources include the 1) cached images from the 2DWG catalog of 2D gel images, and 2) URLs that you enter for any image file on the Web. Note that if your computer has an FTP server, you can compare your own images by copying them to your FTP server and just referencing them with a URL of the form ftp://host/image-file.

Alternatively, a more complex version of this page is 2D gel images from Flicker-Server cache, 2DWG meta-database URLs or ANY Web image URL.

Self-publishing images: This means that users can self-publish their own gel images on their own FTP server. FTP servers are either included or are easily installed on Microsoft Windows95, Windows-NT, Macintosh and UNIX systems which are connected to the Internet via TCP/IP.

Image formats: For now, the images must be GIF or JPEG formatted images. In the future, it will handle TIFF, XWD, PS, PS2 files. Images must be less than about 1.5 Mbytes or they will be rejected.

Web URLs allowed: Only http:// and ftp:// protocols are accepted. Note that image files specified by CGI-BIN locations may not currently work.

Image loading times: Note if you use the explicit URLs, loading will take much longer (could be on the order of minutes) since the Flicker server needs to read the gels from the Internet and then pass them back to Flicker running on your web browser. Gels from the NCI Flicker Server will load the fastest.

Image file names: The gel images listed in the NCI Flicker-Server or 2DWG scrollable selectors below are sorted by 2DWG 'WBnnnnn identifier and are listed with the (tissue-type, species, cell-line). If the 2DWG identifiers and short descriptions are not obvious to you, you may want to search the 2DWG.for the WG identifiers.

Notice:
Because of resource limitations, this server is to be used only for scientific data.

To Flicker compare two gel images:

Flicker Image Comparison: Flicker is a Java program for comparing two images. See the Flicker home page for more information on Flicker.
  1. First select a different image for the Left and Right images. This entails: a) setting the radio button for the source type and b) selecting the particular image from the scrollable list or typing it directly. You may use any of the three from image sources available for both the Left and Right images. Note: you can only compare different images (not an image against itself).
  2. Then press Go Flicker to generate a Flicker comparison of this pair of images.
