What about SC_rate?

"A reliability index derived from sequence and composition identity (defined as SC rate) was evaluated against the
accuracy of each alignment position in a database of sequence alignments compared with corresponding structural alignments.
This showed that there is a correlation between SC rate and the alignment error rate for each alignment position,
indicating that it can be used to predict the alignment's reliability systematically. "
