26 trjcat concatenates several input trajectory files in sorted order.
27 In case of double time frames the one in the later file is used.
30 you will be asked for the start time
31 of each file. The input files are taken from the command line,
32 such that a command like
33 .B trjcat -o fixed.trr *.trr
37 you can simply paste several files
38 together without removal of frames with identical time stamps.
41 One important option is inferred when the output file is amongst the
42 input files. In that case that particular file will be appended to
43 which implies you do not need to store double the amount of data.
44 Obviously the file to append to has to be the one with lowest starting
45 time since one can only append at the end of a file.
50 option is given, the N trajectories that are
51 read, are written in another order as specified in the xvg file.The xvg file should contain something like:
58 Where the first number is the time, and subsequent numbers point to
60 The frames corresponding to the numbers present at the first line
61 are collected into the output trajectory. If the number of frames in
62 the trajectory does not match that in the xvg file then the program
63 tries to be smart. Beware.
