[ccp4bb] diagram of dsDNA

2012-09-05 Thread cuisheng2007
Dear all When I was playing around with Nucplot to generate diagram for dsDNA/Protein complex, the base pairs are displayed as letters. There must be a way of showing the bases as squares, a better illustration, but I cannot find a way of changing it in the "nucplot.par". Does anyone know how to d

[ccp4bb] DNA geometry

2012-08-28 Thread cuisheng2007
Dear all: Is there software or web-server that can measure DNA geometry (PDB coordinates) precisely, such as groove width, helix diameter, helix axis, base tilt angle, helix rise per base pair. It is surely doable to measure and estimate them manually, but I am just wondering if there are better
