Hi,
Is there a utility which can output basic trajectory information like:
- number of frames
- frequency of frame writing
I tried using trjcat on my trajectory which is 27 frames, each frame
written every 2 ps.
% trjcat -f temp.trr
This is the output that I get
################################
Summary of files and start times used:
File Start time Time step
---------------------------------------------------------
temp.trr 0.000 ps 2.000 ps
Back Off! I just backed up trajout.xtc to ./#trajout.xtc.1#
Reading frame 0 time 0.000
lasttime -12345
Continue writing frames from temp.trr t=0 ps, frame=0
Reading frame 20 time 40.000 -> frame 20 time 40.000 ps
Last frame written was 27, time 54.000004 ps
################################
Questions:
1. Why does the last but one line in the output read the way it does ?
2. how can i prevent an output, and get only trajectory information ?
Thank you
-Maria
