gmx-eneconv — Convert energy files
gmx eneconv [-f [<.edr> [...]]
] [-o [<.edr>]
] [-b <real>
] [-e <real>
] [-dt <real>
] [-offset <real>
] [-scalefac <real>
With multiple files specified for the -f option:
Concatenates several energy files in sorted order. In the case of double time frames, the one in the later file is used. By specifying -settime you will be asked for the start time of each file. The input files are taken from the command line, such that the command gmx eneconv -f *.edr -o fixed.edr should do the trick.
With one file specified for -f:
Reads one energy file and writes another, applying the -dt, -offset, -t0 and -settime options and converting to a different format if necessary (indicated by file extentions).
-settime is applied first, then -dt/-offset followed by -b and -e to select which frames to write.
Options to specify input files:
- -f [<.edr> [...]] (ener.edr)
Options to specify output files:
- -o [<.edr>] (fixed.edr)
- -b <real> (-1)
First time to use
- -e <real> (-1)
Last time to use
- -dt <real> (0)
Only write out frame when t MOD dt = offset
- -offset <real> (0)
Time offset for -dt option
- -[no]settime (no)
Change starting time interactively
- -[no]sort (yes)
Sort energy files (not frames)
- -[no]rmdh (no)
Remove free energy block data
- -scalefac <real> (1)
Multiply energy component by this factor
- -[no]error (yes)
Stop on errors in the file
- When combining trajectories the sigma and E^2 (necessary for statistics) are not updated correctly. Only the actual energy is correct. One thus has to compute statistics in another way.
