How to calculate rmsf calculation based on C-alpha (or per...

You need to use the flag -res, if not the default is measured by atom.

I've just found a solution for this:
just need to add flag -res , so the command would be:
gmx rmsf -f md_noPBC.xtc -s md.tpr -o rmsf.xvg -res
then choose C-alpha as a group for rms calculation

You have to create an index:

$ gmx make_ndx -f md_0_10.tpr -o index_ca.ndx

Choose

> 1 & 3
22 Protein_&_C-alpha : 347 atoms

Then, calculate RMSF as follows:

gmx rmsf -s md_0_10.tpr -f md_0_10_center.xtc -n index_ca.ndx -o rmsf_protein.xvg

Generally
For atomic level
gmx rmsf -f md_0_1.xtc -s md_0_1.tpr -o rmsf.xvg
and for residue, you need to flag -res
gmx rmsf -f md_0_1.xtc -s md_0_1.tpr -o rmsf.xvg -res

change .xtc and .tpr file name accordingly.
