refine, use annotations
This parameter is a text string that may be yes or no.
It is known that different proteins have different post-translational modifications. In some cases, proteins may be highly modified by unusual modifications, such as the highly variable modification of histones or collagens. When the parameter is set to yes, an annotation file that contains the modifications known to be present in each protein will be added to the search, on a protein by protein basis. Any other modifications that you have specified will over-ride these annotations, if there is a conflict between the annotation and your specified modification.
