Dear all,

I have appended two .xtd trajectories using a script that was posted in a previous discussion:

my @docNames = ("c30u3-1.xtd","c30u3-2.xtd");

# Create a new trajectory

my \$xtd = Documents->New("T100.xtd");

# Go through each doc and add them to the xtd

foreach my \$docName (@docNames) {

    my \$doc = \$Documents{"\$docName"};

    \$xtd->Trajectory->AppendFramesFrom(\$doc);

    \$doc->Close;

}

The problem merging the trajectories using this script is that the time of trajectories doesn't add sequentially. For example: the two trajectories I want to merge have 900 frames (900 ps) and the final trajectory has 1800 frames which is ok. The problem is that the time goes form 1 to 900 ps and after the first 900 ps it comes again from 1ps to 900 ps, instead of going form 1 to 1800 ps (you can see this clearly if you plot the density of the simulation). Does anybody have a best way of merging trajectories? Thanks!

Best,

Luis
