Biopython SeqRecord

Hi everyone

I`ve a trouble with adding letter annotations into my sequence.
I have a Seq object and a string with secondary structure shortcuts. I want to assign a secondary structure symbol to each aminoacid.

Could you send me an example of letter_annotation's usage for my datatype?

seq = Seq('VLSPADK', ExtendedIUPACProtein())
struct = '---HHHT'

Thank you in advance

You would create a SeqRecord object with this Seq and add the structure string to the record's .letter_annotations dictionary under a key of your choice (eg "structure").

Great!
