Determine what regions of the protein were predicted through ab initio techniques

Thank you in advance for taking the time to answer this question, I'm extremely appreciative.

Is there a method for determining which regions of the submitted sequence were modeled through ab initio techniques?

The I-TASSER website states: "In cases where no appropriate template is identified by LOMETS, I-TASSER will build the whole structures by ab initio modeling."

My understanding of this is that for regions of the protein where no suitable template is found, ab initio modeling is used. Is this correct?

Thank you!
