I also faced the same problem. I ran 100ns simulation of my
protein-ligand-ion complex in TIP3P. I found that the rmsd value for ligand
is not stable so thought of continuing the simulation. But I can not use
the restart file.
I got following error:
ERROR: I could not understand line 22288
119.5803932 241.7497484-572.4462595
I opened the previous restart file and checked for this line. I found that
usually there are 6 coordinates in a line (for 2 atoms, if I am not wrong).
But in the error line there is only 3 coordinate information..

I tried to generate the pdb file from last restart file (using ambpdb) but
it also showed some error.
As an alternative, I took previous trajectory file (prod1.crd) and I tried
to generate the restart file after 50 ns simulation. I managed to generate
the restart file (also ambpdb worked with with this new restart).
BUT, when I restarted my simulation with this restart file, I got following
error:
*ERROR: I could not find enough velocities in restart1.rst*
As Dac suggested, I can use the netcdf format in future. But please let me
know how to restart this simulation 100ns onward???
Thanks,
