The imaging software used to create the figures also may account for the difference in many factors of both the original and the replicate. The original figure was created through Inkscape and the replicate figure may have been created through microsoft word. Imaging size differences could be explained by this software as well as Word limits the margin sizes to one inch by default, whereas in Inkscape, the images are not bound to any range. This could also explain the letter label sizing, as font size 70 in Inkscape may appear differently than font size 70 in Word. Word also does not have the same centering functions of the letter labels as Inkscape, also accounting for this difference between the original and replicate. Discrepancies in arrow shape and size may also be explained by this software difference. In Word, arrows appear blue and naturally thick. In Inkscape, one can edit the arrow color and width. The arrowheads are also different as Inkscape offers a wide range of heads to choose from while Word has the singular arrowhead of 90 degrees. The black line in the interaction image and green backgrounds of images in the replicate figure may also be fragments of Word imaging that Inkscape does not possess.
