When I calculated the molecular dynamics of condensed matter by Forcite and needed to analyze its Dipole autocorrelation function, he showed: Dipole autocorrelation function analysis failed.
The time associated with the selected frames does not increase evenly with frame index., I don't know what's wrong, it's 144 frames, In the Origin Step analysis interface, 1frames 1.0ps.

The origin of the file: I used a Perl script to perform a series of molecular dynamics, the density for its convergence of the judgment object, the current convergence is, will stop the molecular dynamics, so that my series of files in different temperatures of the file frame is not the same.

I would appreciate it if you could solve the confusion for me.
