For length measurement, bshow (part of bsoft) is very nice. I think bsoft should be able to measure angle as well but I've never tried.

Hello,

I have some nice 2D Class averages of my negatively stained particles, now I want to be able to measure lengths and angles - can anyone recommend a program to do this?

Thanks
