How to extract 'Sequence' and 'Producer code' details from an LIS file? #398

Closed AchyuthB closed 2 years ago

AchyuthB commented 2 years ago

Hi,

Using dlisio.dlis module, from a DLIS file, I am able to extract sequence information as logical_file.fileheader.sequencenr

The Origin details I was able to extract using logical_file.origins[0]

But for LIS files (using dlisio.lis), I don't see any details regarding extracting those in their API documentation.

Any help regarding this is highly appreciated.

Regards Achyuth

There is not a 1-to-1 mapping between metadata in LIS and DLIS, but this type of information is typically found the File Header, Tape Header and Reel Header. Sequencenr doesn't really make sense, as the concept Storage Set doesn't exist in LIS. There is also a lot of metadata in the Job Identification-, Tool String Info- and Wellsite Data-records, but these are far less structured and what vendors put there varies
