ImageJ makeLine normalization help

drewstolaf
Hello,

I am analyzing an image of a cell, and I have created a macro that uses the makeLine tool from the center of the nucleus to the edge of the cell in several different directions.

My problem is that each of these lines are a different length, and thus in my results table there are a different number of points (intensity values) for each line.

I was hoping to normalize this data set so that each line contains the same number of points so I can continue with statistical analysis. I have struggled through trying to make the "makeLine" command only take measurements at a specified interval, and I have tried manipulating the data in the results table as well.

Any help would be greatly appreciated!

You could resample the profile to a fixed number of points (100 in the example):

makeLine(10, 10, 50, 30);
profile = getProfile;
profile100 = Array.resample(profile, 100);
