Re: [ccp4bb] Angle between two different helices from two different subunits

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

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. HTH Guenter Hi all I would be interes

[ccp4bb] Angle between two different helices from two different subunits

2009-03-23 Thread peter hudson
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 programm
