You don't necessarily need, or want, a program to do it.
The trick is to determine exactly which points in space you want to use.
If you can select a start and end point for each of your strands and
record their x,y and z, that gives you vectors you can apply some basic
vector geometry to, e.g. to calculate angles between them (based on
their dot product) and other things.

Hi all,
is there a similar software for beta strands ?

Hi Peter,
you can do that with interhlx:
http://nmr.uhnres.utoronto.ca/ikura/resources/data+sw/interhlx/
There is also a way to determine the interhelical angle with molmol,
http://hugin.ethz.ch/wuthrich/software/molmol/
defining cylinders for the helices.

Hi all
I would be interested to know about the programmes which can
calculate the angle between the two helices. I want to
calculate the angle between the two different helices from two
different subunits of the structure. I know a non-supported
programme at ccp4 called helixang. Is this programme can be
helpful? Furthermore, i am not able to understand , how this
program calculates the angle between the two helices of
different subunits, after reading its logfile. I will appreciate
suggesstions.
Thanks in advance
Peter
