[gmx-users] there are fewer frames in your trajectory than there are degrees of freedom in your system.

Dear gromacs users,
                                i tried to analysis trajectory using covar
command (gmx_mpi covar -s *prot_only-apo.pdb *-f *PROTEIN.xtc* -v
eigenvect.trr -xpma covara.xpm)
 i got following warning
*WARNING: there are fewer frames in your trajectory than there are degrees
of freedom in your system. Only generating the first 400 out of 3564
eigenvectors and eigenvalues.*

 kindly provide suggestions weather can i ignore above mentioned warning or
not

thank you
