Hello Dmitry,
The IMAPP virtual appliance uses the software distributed by the NASA Ocean Color Group for the processing that goes from Level 0 to Level 1B. As it it used in the IMAPP VM, it is set up to process the entire pass.
We can try to help you with using the software, but it is distributed and maintained at:
http://seadas.gsfc.nasa.gov/modisl1db/
The execution of modis_L1A_extract.py should be as seen below. I think you need to include the prefixes including -g , -n, -s, -w, -e.
Good luck,
Kathy
Usage:
modis_L1A_extract.py [OPTIONS] L1AFILE [-g GEOFILE] [-o EXTRACTFILE] -n NORTH -s SOUTH -w WEST -e EAST
if GEOFILE is not provided, assumed to be basename of L1AFILE + '.GEO'
or
modis_L1A_extract.py --par parameter_file [OPTIONS]
Options:
--version show program's version number and exit
-h, --help show this help message and exit
-p PARFILE, --parfile=PARFILE
Parameter file containing program inputs
-o EXTRACTFILE, --output=EXTRACTFILE
Output L1A extract filename - defaults to L1AFILE.sub
-g GEOFILE, --geofile=GEOFILE
INPUT L1A GEOFILE filename - defaults to basename of
L1AFILE +'.GEO'
-n NORTH, --north=NORTH
Northernmost desired latitude
-s SOUTH, --south=SOUTH
Southernmost desired latitude
-w WEST, --west=WEST Westernmost desired longitude
-e EAST, --east=EAST Easternmost desired longitude
--extract_geo=EXGEO extract geolocation filename
-v, --verbose print status messages
--log Save processing log file(s)
==========================================================================
The modis_L1A_extract.py script extracts a Level 1A subscene from an Aqua or
Terra L1A and GEO file. If an output GEO file is specified, the script will
also create a GEO file corresponding to the new L1A subscene, since the
original GEO file will not work with the new subscene.
==========================================================================
======================================
Explanation of command line arguments:
======================================
L1AFILE (required)
Input MODIS Aqua or Terra L1A file to be extracted.
GEOFILE (required)
Input MODIS Aqua or Terra Geolocation file. If not provided on command line,
the basename of the L1AFILE + '.GEO' is assumed.
EXTRACTFILE (required)
Filename of the output L1A extracted subscene. If not provided, L1AFILE.sub is
used.
