I tried changing the colvars from character to factor, but that didn't help. I'm using R2.10.1 and either WinXP or Win2000.

Do anybody have any idea to how to use this package to speed up the simulation? I really appreciate your help. Have a nice day Sincerely, Yinding Wang [[alternative HTML version deleted]]
