The atomicfluct command measures fluctuations over all input frames,
so it is doing what it is supposed to do. Are you sure you don't want
to calculate the RMSD of the ligand to the reference? (It's not clear
to me how calculating fluctuations over 1 frame is helpful.)
Assuming RMSD is indeed what you want, just do something like:
reference crystal.crd [REF] parm crystal.prmtop
rmsd RMSD :
1-578.CA,C,N,O ref [REF]
rmsd Ligand :ligand nofit out ligrmsd.dat
The 'nofit' keyword will ensure your previous alignment of the protein
to the reference is not altered. Hope this helps,
