According to the dictionary the template_seq_id_begin and template_seq_id_end fields have to be integer values. However they are set with a ? symbol:

IHM follows the spec and fails with the error:

   1542         identity = ihm.startmodel.SequenceIdentity(

TypeError: int() argument must be a string, a bytes-like object or a number, not '__UnknownValue'

@brindakv what is the best course of action in this case?

[brindakv]

template_seq_id_begin and template_seq_id_end are not mandatory fields and therefore can be set to ?.

then I presume this qualifies as an ihm bug for @benmwebb
