No split frequencies were shown in terminal when Mrbayes were set as " 1 runs and 8 chains"

Question

Hello, everyone

I met a problem and have no idea to explain it, the detail is split frequencies of Mrbayes were shown in terminal with " 2 runs and 4 chains" setting in scripts and not shown with " 1 runs and 8 chains". I don't know why and what it means, and I guessed that " 1 runs and 8 chains" may be a wrong setting.

If you have some suggestions, please tell me.

Best

Split frequencies are only calculated between independent runs. You will not get split frequencies with only a single run.
