I hope I'm doing this reply correctly [this is my 1st reply].
To Melissa: No I'm loading a JPEG image, not a NEF.
YES! The File>Save As>Text Image creates a text file organized the way I
want. Thanks. But it has no headings on either axis. I may not need them,
but in the Measurements.txt file that I created 2 weeks ago, there was a Yn
column and an Xn row to ID the data. Any clue how to get those?
Thanks.

I assume that you are starting with a Nikon RAW file (.nef). What you need
to use is the DCRAW plugin
<
https://sourceforge.net/projects/ij-plugins/files/ij-dcraw/> that I think
is automatically installed with Fiji. Run the plugin either from the menu
Plugins->Input-Output->DCRAW or from the Command Finder. Make sure the
following two options are checked: a) Do not automatically brighten and b)
Document mode without scaling. Also make the Read As popup say 16-bit
linear. This should read the raw sensor data in without changing the
grayscale values.

From the menu, click File->Save As->Text Image... You will end up with a
tab-delimited file with the grayscale values.
