Macro or method to get at multiple profiles at once?

[ldsdbomber]

I have an image containing a field, and want to analyse 40 profiles across
it, i.e. looking along MLC travel directions on a linac. Is there not an
easy way or macro for me to be able to have a predefined set of 40 positions
such that I can open an image, load all 40 profile ROIs, and get the plot
profile data saved to a file, or at least opened so that i can copy it.
 
has anyone attempted such a thing?

This macro will walk through all line ROIs in the ROI Manager and print the corresponding ROI name plus the profile values as a tab-separated text. Does this help you?


// walk through all ROIs in the ROI Manager
nROIs = roiManager("count");

for (iROI = 0; iROI < nROIs; iROI++) {
        roiManager("select", iROI);
        dProfile = getProfile();
        sLine = call("ij.plugin.frame.RoiManager.getName", iROI);
        for (i = 0; i < lengthOf(dProfile); i++) sLine = sLine + "\t" + dProfile[i];
        write(sLine);
}

Hi, thanks a lot for that. and it's possible to save a bunch of ROIs then and have them automatically open or load them with another macro first?

ImageJ Macro Language supports also loading of ROIs into the ROI Manager:
roiManager("Open", fileName);

You'll find more information on the ImageJ Macro Functions site:
