I had simulate the system which contain around 30,000 beads by using NVT ensemble for 1000,0000 steps with snap shot of each 1000 steps.

I found an error when I want to analyte results such as concentration profile of selected set, MSD but it work only analysis tool in Statistics category.

The error reported that "Concentration profile analysis failed. There are np particles to work on."

Is any one found this kind of issue like me?

PS. Previouly, I found that MS5.5 cannot read the trj which the size larger than 2GB, I can not play back animation nor analysis any this from it, So I guess this issue also might be from limitation for beads containg in PBC cell
