Hello,
long time since last post.
We are trying to process MERIS FR ESA N1 to L2 using SeaDAS VM.
But after downloading/installing seadas_meris
when trying to run the process job interactively
we've got error message, such as:
L2GEN_DEFVAL Cannot find: $OCDATAROOT/octs/msl12_defaults.par
even after downloading/installing seadas_octs, than:
L2GEN_DEFVAL Cannot find: $OCDATAROOT/modist/msl12_defaults.par

So, this this means we should install all the tar files?
Or is there any other thing that could be done?
Thanks in advance,
Milton

Sounds like you are missing the seadas_processing.tar.gz file. 
This file contains the files that SeaDAS is complaining about
being missing.

To process any mission, you need this file and the mission specific tar file.
You do not need ALL the mission tar files (unless you wish to process all
missions).

Sean,
Thanks. of course you were right.
After completing the installation, we could display
successfully a MERIS-FR ESA-N1 image
(locally generated by our own processor,
as INPE has an authorized receiving station for MERIS FR data).
Unfortunately, we can not generate a Level-2 image properly (!?)
Here is the Error message, when selecting an image file
for L1-L2 processing:
"SeaDAS Version 6.0 (pid = 14710)
GENERIC_FILE_TYPE detected a non-HDF file.
GENERIC_FILE_TYPE detected an ESA-formatted MERIS file.
Getting MERIS - "radiance_3" data from HDF file...

Even with this Error message, we've tried to proceed with the Level-2 processing.
(using climatologies instead of best anc data)

The processing continued apparently well.
But, when displaying the generated Level-2 image, we can only get " flagged"
or invalid data (Raw -32767 for chl and Rrs_510, as an example)

Any suggestion and/or comment about this issue?
Maybe we should send you one of our " meris.N1"  file?!
Thanks in advance for your attention,
Regards, Milton

Milton,

The getanc problem is the result of the filename.  It differs from our standard format.
getanc tries to use l1info to get the start/stop times to select the appropriate ancillary
data, when that fails it falls back on the filename.  Neither the MERIS N1 file format
nor the MERIS filename work so getance fails.  You can call it by specifying the
start time directly - see the usage for how (call it with no arguments).

As for the L2 processing failure - could you attach the log output?
We may also need an example file.  Send instructions as to where to access a file
to seadas at seadas.gsfc.nasa.gov

Regards,
Sean

OK.  The problem is that the 'SUSPECT' flag is set for every pixel in the scene.
When reading MERIS N1 files, l2gen will not processes pixels with 'SUSPECT'
or 'INVALID' L1 flags set.  I cannot explain why the entire scene is flagged as
'SUSPECT'.
