Hi Gromacs Users
I want to plot SAS of residues with errobar.
I want to know what is the meaning of third column in file of residue.xvg
(output of g_sas)?
which of the following expression is true about third column?
1) first answer=sqrt(summation(s_i - s_mean)/(N-1)))
2) second answer= first answer/sqrt(N)
N is the total number of frames.
In other words, is it necessary that third column be divided by sqrt(N)?
Thanks for your response.
Meisam
