Just some FYI,
I ran a lammps job using the latest windows executable on a windows box that created a couple binary restarts, then tried unsuccessfully to use the restart2data that came with the 3Oct10 lammps version to convert the binaries to data files on another machine (cygwin).
I got the error message, “invalid flag in header section of restart file”.
Downloading and using the restart2data from the 5Mar12 lammps distribution solved the problem.
any additional guidance welcomed,
