[gmx-users] XTC.error

[He, Yang]

Hi all users,

When I run the mdrun command, it always shows that XTC.error. Then I check the md.log file and find that:

There are 220 atoms in your xtc output selection
   Energies (kJ/mol)
           Bond       G96Angle    Proper Dih.        LJ (SR)   Coulomb (SR)

Program mdrun, VERSION 3.3.1
Source code file: stat.c, line: 257

Fatal error:
XTC error

The total energy is shown"nan" I also checked my gro file but there are no lapped atoms. And when I run the command "grompp", there is no any warnings.

Can anybody tell me what is the problem about this error?

Thank you very much.
