I am having some trouble running the idl command l1agen_modis.
This command first makes a call to modis_L1A.csh, which calls modis_atteph_py and modis_geocheck.py.
The latter call seems to cause my problem.
The logging below shows correctly that A2011190095500.L1A_tmp is the input for modis_atteph_py.
The logging below shows correctly that A2011190095500.GEO_tmp is the input for modis_geocheck_py.
However modis_geocheck.py uses A2011190095500.L1A_LAC to determine platform type,
where - I think - it should use A2011190095500.L1A_tmp instead.
The problem here is that modis_geocheck.py attempts to guess the name of the L1A file from
the name of the GEO file and fails to come up with the right answer!
In the code of modis_geocheck.py I read that the extension of the L1A file name is always L1A_LAC.
Can someone confirm this and propose a solution.

Regards, Gerard

Indeed, there was a bug.  Please replace modis_geocheck.py with the one posted in this thread:

http://oceancolor.gsfc.nasa.gov/forum/oceancolor/topic_show.pl?pid=17450;hl=#pid17450

You may also want to replace modis_atteph_utils.py and ProcUtils.py, posted earlier in the same thread.
