I don't get it. Do you need imaging program to be able to scan
you gel and then digitize/edit it or you need to calculate MW?
The latter does not require software: plot log(MW) vs distance
and from this calibration curve (ideally,line) calculate
MW of you protein. There are many caveats discussed in many
sources but software just can't help here.
