Re: [ESPResSo-users] gyration tensor

[Peter Košovan]

Dear zeinab,

set gyration_tens [analyze gyration_tensor $typeid]

puts $gyration_tens

set rg [lindex $gyration_tens 0]

puts $rg

and you will understand your problem.

With best regards,

peter

Hi

I need to calculate gyration radius of the star polymer .I,m using :

set gyration_tens [analyze gyration_tensor $typeid]

set rg [lindex $gyration_tens 0]

but it returns Rg^2 (output isn,t number!!!!)

Can you explain about output of gyration tensor?

thanks
