[Bioperl-l] SeqIO-based parser for Vector NTI sequence files

Hi Scott,
It is my understanding that Informax developer used the COMMENT line to encode molecular level attribute-value pairs.
i.e. your VNTDATE|<integers here>|
Some dialect of LISP had a role in the products back-days. The attribute 'Vector_NTI_Display_Data_(Do_Not_Edit!)' is a LISP S-expression whose CAR is 'SXF' (ever program LISP?).
It should be easily 'parseable' by any LISP interpreter or anything that can balance parens.
The only 'rub' is the #NNN= tokens which appear to be some form of forward reference used by the lisp serializer to allow for internal references.
I would be very surprised if you could learn from ABI (was Invitrogen, was Informax) anything about the internal structure of this. I once asked about 5 years ago. I am/was a supported user. It was arcane historical knowledge even then.
I would also be very surprised if there was anything in it that was meaningful, unless the creator of the molecule in VNTI was using some very odd convention.
I used to know which dialect of LISP was being used by them and might track it down if it were important to you....
If you are after the oligo descriptive text in the COMMENT, it is likely that the oligos ALSO have a genbank feature associated with them. But you probably already looked....
What are you really after...?
One thing you should know (if you don't) that might bear on your underlying problem (whatever it may be....). Vector NTI can open GFF files and display them as an extenral analysis. The element of the analysis can then be promoted interactively by the user to be features (genbank style).
