i wish to determine the persistence length of double strand DNA with different bases (10 to 150). i found an equation:
P= B_s/ K T where B_s is the bending stiffness
and B_s= E * I where I is the cross sectional area

So, i just need to determine cross section of double strand DNA.

Also, has anyone ever used oxDNA on Python before? i want to determine the persistence length on oxDNA as well to be able to compare the values

Well, i am currently exploring oxDNA. And for the cross section, i wonder if i should take that of a cylinder or circle..
