[gmx-users] normalized overlap

I am trying calculate the degrees of overlap of subsets of a simulation to the whole trajectory by following the explanation in the manual of gmx anaeig:
"When -v, -eig, -v2 and -eig2 are given, a single number for the overlap between the covariance matrices is generated...."
Although, it does not make any difference whether I use or not the "-eig" and "-eig2" inputs, the results for normalized overlap are the same. In other words, the normalized overlap is not calculated by using the equation given in the manual:
"normalized overlap = 1 - difference/sqrt(tr(M1) + tr(M2))
where M1 and M2 are the two covariance matrices and tr is the trace of a matrix."
Has anyone else found this problem?
