Hi all, When calculating the average number of hbonds during a simulation, does the program g_hbond contemplate the possibility of an atom involved in two hbond? If I visualize the structures with molden, setting the same cutoff criterion for hbonding than g_hbond utilizes, I found out that some O

Dear all, I am doing PCA on a 110ns run. When calculating the subspace overlap from independent PCA performed in different time windows, I expect the overlap to be 1 only when the time interval is equal to 110ns, since both covariance matrices are identical. However, I found that from the interval
