Has anyone used any commands to dump out in his/her wanted style?

Please reply to the mailing list, not to me, thanks.

dump 1 all custom 5 dump.coordNVT id type x y z

If you use this instead:
dump 1 all custom 5 dump.coordNVT.* id type x y z

you can get one dump file per snapshot.

If that’s too many, then do something like:

dump 1 all custom 5 dump.coordNVT.1 id type x y z

run 100000

undump 1

dump 1 all custom 5 dump.coordNVT.2 id type x y z

run 100000

undump 1

dump 1 all custom 5 dump.coordNVT.3 id type x y z

run 100000

undump 1

etc
