Dear Gromacs users

I have one big problem with g_clustsize!

I see 9 micelles in my system after running. When I use g_clustsize for number of clusters and average cluster size, they don't emphasize each other, and I see 9 micelles from 360000 ps to 1200000 ps in my box, but results of nclust.xvg is not regular and have very fluctuations. I examine these results in different -cut. Please see my results:

Whereas the size of clusters in the box are similar when I see with ngmx. I don't know where is my problem!!!


May I ask you to help me Please?
