I'm looking for an image analysis program running on UNIX that will allow
me to do video densitometry on digitized images of polyacrylamide gel
electrophoresis gels.  What this means is I will be working with an image
with a series of 'bands' of varying intensity, and I will need to be able
to draw a line through this image and get a plot of intensity versus distance
along this line, a plot that should contain a series of peaks corresponding to 
the bands on the original gel.  Next I need to quantitate the data by 
integrating the area under each of these peaks.  Is there such a program
floating around in one of the anonymous ftp archives, or otherwise available
for use on a UNIX machine?  There are a few such programs to run on the
Mac, but I don't have access to a machine that will handle the necessary
grey scales.

Thanks in advance,
