      Not really! You are effectively stitching on a spherical surface.
      This doesn't have any "ends". The four images all overlap with their
      two neighbours to give four overlap areas and there should be control
      points assigned in all four of these areas. This will ensure that
      the images can be aligned with each other by the optimizer.

      When you generate the 360x180 equirectangular image, there will then
      be two "ends" at the left and right hand edges. If the blender does
      its job properly, these two edges should produce an invisible join
      when butted together. Exactly where this invisible seam occurs in
      the panorama can be changed before stitching by rotating the whole
      composite panorama image in PTGui using the numerical transform tool
      to adjust the yaw.

      From what you say, it may be that you have overlaps between images 0-
      1, 1-2, 2-3 but not 3-0. If there are no matching features between 3-
      0 (and the area is not actually featureless) then you have presumably
      not taken the shots at the right angles of yaw. Is this happening on
      just this one set of images or on different panoramas?
