Hmm, it doesn't seem to work with tran1.xx, tran2.xx, tran3.xx, ... I get "no such vector". 🤔 Oh wait, they are tran3, tran4 and tran5. Why would that be? Are the numbers shared between the various types of analysis? But I had done 3 ac analysis before, ac1, ac2 and ac3, why would tran begin at 3 then? Odd. Also, if I do "restart" I get "restart: no such command available in ngspice".
