dealing with a very long, thin image (6955 pixels * 16 pixels)

[Rafael Carazo-Salas]

Dear ImageJ users I am currently analyzing very long , thin images  
(say 6955 * 16 pixels !)  .  In order to view one such image at 100%  
scale , I use the magnifying glass and then move along the image  
using the hand tool (I can only view a limited stretch at a time ) .  
So far so good .  The problem comes when and I try to make a  
segmented line selection that spans the whole length of the image  
using the zoomed image .  I can draw a selection , but then when I  
use the hand tool to move to the next stretch ("panel") the segment  
line selection is lost .  Does any one of you have an idea of how to  
overcome this problem ?  Thank you very much in advance for any  
feedback with this !  Kind regards ,

Maybe from the macro editor (Plugins>New... Macro) :

makeRectangle(xMin, yMin, xMax, yMax);

to define the selection, then do whatever you need to do.
