Hello Paul,

Did you generate your mdcrd file with AMBER14 or AMBER16? If on AMBER14, did you try using ioutfm = 1?

I'm having trouble getting sander to work with imin=5 (post-processing trajectory files). I have attached a simple test case which works fine for AMBER14, but not with AMBER16.

Sander crashes before outputting any energies, with the following error message:

sander: posixio.c:232: px_pgout: Assertion `*posp == ((off_t)(-1)) || *posp == lseek(nciop->fd, 0, 1)' failed.

Program received signal SIGABRT: Process abort signal.
