I would really need the error message since there is no trace of<BR>
a "pyMRT" error message in r.modis.*<BR>
<BR>
Perhaps you mean pyModis? This is part of the module set.<BR>

I was in contact with Gail Schmidt (MRT developer) from NASA about this<BR>
years ago (MODIS V003 and V004 when MODIS was still in ISIN, I posted<BR>
that to gdal-dev some years ago but didn't gain much attention ...<BR>
For ISIN (nowadays MODIS is in SIN), the source code is here:<BR>
mrt4.1/MRT/resample/calc_isin_shift.c<BR>
<BR>
I am not sure about any potential projection shifts in SIN (MODIS V005),<BR>
but the source code of MRT is available if anyone wants to investigate.<BR>
Or run comparative test cases in different parts of the world....<BR>
<BR>
For r.modis.* we decided to take the secure route and used MRT.<BR>
