Hello everyone!
We have a problem to produce L1B files after having L1A in MODISL1DB 1.8 software. there was no problem with previous versions.
here are PCF quotation from (*LogReport*) output error for that process (something with calibration fields). Did anyone faced with this. Did not find how attach files... sorry

Alexey -

You can attach files only after you post the text; a button will appear below.

Are you sure the L1A and geolocation processes (l1agen_modis, geogen_modis) completed successfully?  You may want to do a "ncdump -h" on the output files to make sure.

Are you sure you installed the latest calibration tables?  There should have been a file with the suffix ".pcf" left in the processing directory; please attach that, the LogStatus file, and the full LogReport file (if there's more than you already posted.)

Thanks for the info.  Now I'm starting to suspect the geolocation processing, since the L1A file metadata does not have a valid orbit number.
Please post the GEO Log* files, and the ncdump output for the geo file.
Do all files fail L1B processing, or is it just this one?

Ok, I added -  it seems bad time packets  but why? I ask producer
- By gfireman Date 2014-04-22 13:43
Indeed; all scans are incomplete.  I'd missed this from the L1A dump:
    :Number of Scans = 324 ;
...
    :Incomplete Scans = 324 ;
    :Missing Packets = 981960 ;

If it's only this pass that can't be processed, you can get the data from our archives.
If all passes fail, then you'll have to look further into the problem.

yes - it's global problem. But producer of PDS said that this file was successfully converted with some previous IMAPP version.
Ok we will investigate "unpack" procedure... on the early of MODIS I also programmed this procedure but now slightly forgot what it was )))
Thank you.
