Dear Gromacs specialists, Can you help me about g_dist? I have a micelle system, I want to obtain distance between center of mass of micelle with the last of carbon bounded to head group in surfactant.
It should be near 2.2 but when I did "g_dist -f md.xtc -s md.tpr -b 150000 -o dist.xvg" and then selected micelle and the last carbon bounded to head group, respectively , and next did "g_analyze -f dist.xvg -av" it give me : std. dev. relative deviation of standard --------- cumulants from those of set average deviation sqrt(n-1) a Gaussian distribition cum. 3 cum. 4 SS1 5.324286e-02 2.182349e-02 3.984406e-04 0.287 0.064 SS2 -2.000683e-04 3.327947e-02 6.075972e-04 0.045 -0.036 SS3 -6.405102e-04 3.270624e-02 5.971315e-04 0.001 -0.052 SS4 -2.777796e-04 3.366480e-02 6.146323e-04 0.016 -0.013 What should I do for obtain correct distance?
