I need some clarification on the sequence identities obtained after structural alignment using TMalign

Hi all,

I am conducting an analysis of protein sequence-structure relationships. I performed an all against all structural alignment using TMalign and would like to know if the sequence identities output by TMalign are equivalent or comparable to those from Blast or any other sequence alignment tool. I would like to use these sequence identities to generate RMSD-Sequence identity plots.

Thank you.
