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
