[gmx-users] extending simulations

[Myunggi Yi]

Dear users,

I am using gromacs2018

I've got the following error message.




Command line:
  gmx convert-tpr -s md1.tpr -f md1.cpt -n ../index.ndx -o md2.tpr -extend
20000.0


-------------------------------------------------------
Program:     gmx convert-tpr, version 2018
Source file: src/gromacs/commandline/cmdlineparser.cpp (line 276)
Function:    void gmx::CommandLineParser::parse(int*, char**)

Error in user input:
Invalid command-line options
    Unknown command-line option -f




The option is valid.

Is this a bug?

Thank you for any help, in advance.
