If there are no regular intervals but if you know in advance the timesteps when you want to output data, you can use a separate file containing the timesteps, and write:
variable a file timesteps.in
variable b equal next(a)
dump 1 all xyz 5 foo.xyz
dump_modify 1 every v_b
Just adapt this to whatever you want to output. Your timestep.in file would look like this for instance:
1
3
423
5232
If you have minimizations in between, just use reset_timestep and multiple timesteps files.
