I'm trying to process a full directory of raster images (MODIS HDF files).  One processing step is the georectification of the images for which I use warp.

When I run the process ArcGIS returns this annoying message which I can't dechipher:

Executing: Warp C:\GeoPhysical\Chlorophyll\Modis_1day_4km\HDF\2007\Temp.img '-0.5 -4319.5';'-0.5 0.5';'8639.5 0.5';'8639.5 -4319.5' '-180 -90';'-180 90';'180 90';'180 -90' C:\GeoPhysical\Chlorophyll\Modis_1day_4km\World\2007\A2007166_L3m_DAY_CHL_chlor_a_4km_World.img POLYORDER1 NEAREST

ERROR 999999: Error executing function.
A locator with this name does not exist.
Failed to execute (Warp).

Does anybody know what the "locator" refers to ?

The input (temp_Raster) is valid and the sourcePoints and targetPoints + other parameters originate from a working ModelBuilder version of the script !
