Joseph, This is fussy for the first image, but can then be repeated easily for the other 19, or a script can be saved, edited and run: 1. Create a ternary image of one grid and use the colour tool to set up the colours as you want them. 2. With the image colour tool, for each band separately save the colour table as a .zon file. To do this, select the band, click on the Transform/Save to file icon, change the file type to *.zon and then save the file. Zon files include colours and the data ranges. You can call them K.zon, U.zon or TH.zon, for instance. Now you have the three zone files for each radioelement. 3. Use "Grid/Display grids/3-grid composite", and display your next image using the .zon files just created (change the file type to *.zon in the colour table browser). The first time you need to change the directory to your workspace directory since this is likely where you saved the *.zon files (the browser looks in Geosoft by default). 4. Display the other images. The zon files will already be defined in the 3-grid composite GX so it is just a matter of specifying each three-grid set. You could also save this as a script and edit this to create a script to display all 20 grids. Hope this helps...

I know how to use the image tool to accomplish that but it is very time consuming and this is a repetitive task that I expect to do many times. I am looking for some way to automate this process and have not been able to find a way to do it. Does anyone know of a way to accomplish this? -------------------------------------------------------- E-mail: Joseph Duval<[EMAIL PROTECTED]> Phone: 703-648-6327 FAX: 703-648-6383 Date: 07/26/99 Time: 17:45:49 U.S. Geological Survey 12201 Sunrise Valley Drive, MS 954 Reston, VA 20192 -------------------------------------------------------- _______________________________________________________ More mailing list info http://www.geosoft.com/support/listserv/index.html _______________________________________________________ More mailing list info http://www.geosoft.com/support/listserv/index.html
