Note: Since with most 1-D gels you are more concerned with resolving bands in
the vertical direction than the horizontal direction, you may want to
reduce the file size by making rectangular pixels. That is, keeping the
pixel size in the “y” dimension the same, while increasing the size in the
“x” dimension. This lets you decrease the total number of pixels and
therefore file size without sacrificing detail.
When you are finished, click on the OK button.
A pop-up box will give you the option of reducing the file size of the
displayed image or making a copy of the image and then reducing the copy’s
size.
Reducing the file size is an irreversible process. For that reason, we suggest you
make a copy of the image and reduce its file size. That way, if you lose too
much resolution, you can simply delete the copy and try again. Once you are
happy with the reduced image, don’t forget to delete the original. The goal is
to save space!
