outp_shp_fname)
|
reference_seeds_shp |
Point shapefile of reference seeds |
target_seeds_shp |
Point shapefile of target seeds |
target_ref_ID_pairs |
A two-column table that provides in the first column the FIDs of points in target_seeds_shp and in the second column their equivalent FID in reference_seeds_shp |
outp_shp_fname |
Filename for a .shp file to which to writ the results |
A SpatialPoints object with the points in reference_seeds_shp stretched to match the target point cloud. The X and Y coordinates of the original points in reference_seeds_shp are saved as the fields primalX and primalY in the attribute table of the output
