[gmx-users] trjcat eneconv time continuation

[Tsjerk Wassenaar]

Hi David,

You should have as many lines with a 'c' as you have trajectories.

Cheers,

Tsjerk

Sorry that my query wasn't detailed enough. Trjcat yields a Fatal error
(Error reading user input). Here is what I tried, considering the first 2
trajectories (the errors are the same if you consider more than that):

Option 1:
echo c | trjcat -f traj1.xtc traj2.xtc -o traj_1_2.xtc -settime

Option 2:
trjcat -f traj1.xtc traj2.xtc -o traj_1_2.xtc -settime << EOF
c
EOF

Option 3:
trjcat -f traj1.xtc traj2.xtc -o traj_1_2.xtc -settime < choice.txt

Where 'choice.txt' contains the letter 'c' in one line.
The log in any case is the following:

Enter the new start time (ps) for each file.
There are two special options, both disable sorting:

c (continue) - The start time is taken from the end
of the previous file. Use it when your continuation run
restarts with t=0.

l (last) - The time in this file will be changed the
same amount as in the previous. Use it when the time in the
new run continues from the end of the previous one,
since this takes possible overlap into account.

          File             Current start (ps)  New start (ps)
---------------------------------------------------------
                traj1.xtc        0.000 ps
traj2.xtc        0.000 ps

Program trjcat, VERSION 4.0.5
Source code file: gmx_trjcat.c, line: 178

Fatal error:
Error reading user input
-------------------------------------------------------

"Yeah, a Wuzz, Or a Jerk" (F. Black)



This is with version 4.0.5, when using version 4.5 the log only differs in
the line of the code where the error occurs (201 instead of 178).

Best,
David.
