Retrieve header info?

[ronammar]

Is there a way to retrieve header info that corresponds to the record attributes in the INFO field?

I'm not sure if I understand you correctly, but say you have an INFO field NS in a record (record.INFO['NS']), you are interested in the definition of NS as presented in the VCF header?

Then, yes, you can do something like this:

>>> reader = vcf.Reader(filename='test.vcf')
>>> reader.infos['NS']
Info(id='NS', num=1, type='Integer', desc='Number of Samples With Data', source=None, version=None)
>>> reader.infos['NS'].num
1

Please reopen this issue if that doesn't solve your problem.
