MLP Process MODIS data to L2 data with 250m resolution

Hello.
I tried to use MLP to process the MODIS L1A data to L2 (Rrs or Rhos) with 250m resolution. but each time when i run the process it will skip run l2gen progress.

Here is the Parfile:
# Sample par file for multilevel_processor.
[main]
ifile=/home/model/TEST1/flist.txt
overwrite=1
deletefiles=1
use_ancillary=1

[level 1b]

[l2gen]
l2prod=rhos_nnn Rrs_nnn
suite=OC
resolution=250
# final processing level

So,I don't know why? But when I run the parfile without "resolution=250", it works,the output file with 1Km resolution .

Here is the logfile:
root@model-Precision-7920-Tower:/home/model/SeaDAS/ocssw/bin# ./multilevel_processor /home/model/TEST1/mlp-aqua-l2gen.par --output_dir=/home/model/TEST1

l2gen needs AQUA_MODIS_QKM.*.L1B.hdf + geo files to generate L2 data with 250m resolution. Currently, MLP is not smart enough to choose AQUA_MODIS_QKM.*.L1B.hdf instead of AQUA_MODIS.*.L1B.hdf, therefore MLP won't be able to generate L2 (Rrs or Rhos) with 250m resolution from MODIS L1A data.
