Hello All,

I am running dynamics using DMSO solvent by applying belly to a small
peptide. It is running without any problem when at after 17000 steps it
stops writing in the out file.

There is the following error message:

Input/Output Error 173: Input/output error

   In Procedure: corpac
        At Line: 55

      Statement: Formatted WRITE
           Unit: 12
   Connected To: md_pept_DMSO_bellynew.crd
           Form: Formatted
         Access: Sequential
Records Read : 0
Records Written: 267809

Current I/O Buffer:

  20.924 23.656 18.163 22.578 22.881 17.952

End of diagnostics

The input file is as follows:
     imin=0, ntx=1, nmropt=1,
     ntwr=1000, ntwx=100,
     ntf=2, ntb=2, cut=12.0, ibelly=1,
     nstlim=100000, dt=0.001,
     temp0=300.0, tempi=0.0, ntt=1,
     ntp=1, taup=2.0, npscal=1,
   type='TEMP0', istep1=0, istep2=10000,
                 value1=0.0, value2=300.0,
   type='TEMP0', istep1=10001, istep2=100000,
                 value1=300.0, value2=300.0,
#Hold the peptide fixed
RES 9 514

Does anyone know why data stopped rolling into the out file?
Thank you very much for your help

Best wishes,
