Dear users,
recently i am facing this error
ERROR: Illegal dump_modify command (…/dump.cpp:882).
when i run the script below

please check the documentation:

format args = line string, int string, float string, M string, or none
  string = C-style format string
  M = integer from 1 to N, where N = # of per-atom quantities being output

there should be either "line", "int", "float", a number or "none"
following the "format" keyword.
