eneconv(1)

NAME
eneconv - converts energy files VERSION 4.5.4-dev-20110404-bc5695c

SYNOPSIS
eneconv -f ener.edr -o fixed.edr -[no]h -[no]version -nice int -b real -e real -dt real -offset real -[no]settime -[no]sort -[no]rmdh -scalefac real -[no]error

DESCRIPTION
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 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.

KNOWN PROBLEMS
- When combining trajectories the sigma and E2 (necessary for statistics) are not updated correctly. Only the actual energy is correct. One thus has to compute statistics in another way.
