Have you tried the suggestion:
Pore radius at initial probe position is infinite. Consider increasing the maximum pore radius with -pf-max-free-dist or set an appropriate cutoff for neighbourhood searches explicitly with -pf-cutoff.
Hi Channotation/Chap Can you please provide an example cut off file. I tried to give manual pore coordinates to keep probe radius. But I don't know why it keeps happening. Chap can hardly read trajectory of about 40ns. It terminates with the same error again. Even when there is an obvious single channel in transmembrane protein.
