Stitching images using their X and Y coordinates

Hello everybody! Can somebody recommend a good tool/library for R/Python/MATLAB to stitch stacks (multichannel images acquired with Imaging Mass Cytometry), please? These images have no overlapping borders (if there is an overlap, it is 1pixel or so) and I have the X, Y coordinates. Ideally, I would like to stitch them according to the coordinates. Thank you very much! Any suggestions is very well appreciated. :smiley: :smiley:
