[gmx-users] "Specified frame doesn't exist or file not seekable" when using .xtc

[Qiao Baofu]

Hi,

I am using Gromacs 3.3.1.  The .xtc file is obtained from mdrun, as shown in
the following

; OUTPUT CONTROL OPTIONS
; Output frequency for coords (x), velocities (v) and forces (f)
nstxout                  = 0
nstvout                  = 0
nstfout                  = 0
; Checkpointing helps you continue after crashes
nstcheckpoint            = 0
; Output frequency for energies to log file and energy file
nstlog                   = 1000
nstenergy                = 100
; Output frequency and precision for xtc file
nstxtcout                = 10
xtc-precision            = 1000
