Dear gmx users,
I was analysing some trajectories (without any problem), and then just for
testing, i used gmx check on them, and i got several warnings:

Are this warnings that ‘bad'? Should i run again my simulations? Again, just
seeing them by VMD, and by making some analysis on them with several gromacs
tools(trjconv, msd, rdf, etc) i didn’t see any problem, or get any
error/warning message, so i really don’t know what could be the problem (or if
there is one, i don’t know how to fix it).
Dump out one of those frames with trjconv and see if finding that particle is
illustrative of anything.
In reality, I doubt this is actually a problem because it just means that you
(infrequently) have one particle exactly at the origin.

Hope someone can help me,
Best,
Carlos
ps- I tried to remove pbc conditions of the system, but i’m still getting the
same error:
