hi everyone

say if i want to combine many trajectory files into one files to make a
movie, but i only want selected trajectories, let's say i saved the
coordinates every 100 steps, however, i dont want all the steps to be
included coz the movie will be too long (the files are very huge) .. so i
would like to select only coordinates saved every 1000 steps to be included
in the combined files. but i dont know how to do that.. can somebody help
me?

here is my ptraj file

trajin fr1_.crd.gz
trajin fr2_.crd.gz
trajin fr3_.crd.gz
