　　I'm using Image J software on MR　image to calculate the distance between some structures. I would like to ask, which unit of lengths Image J use to straight line. I didn't enter that distance in the Analyze/Set Scale dialog box, I only
calculated many, and many images and now I don't know what kind of unit (mm, cm, pixel size) the software uses in this case.
    One more problem is because the original size was 128x128 pixels and I resized to 512x512 pixels to calculate the distance using the straight line on tool bar.
    I will appreciate very much your help and also your suggestion.
            Best Regards,
