Dear David, you could write a minimalistic shelxl ins-file and use the covalent radii from there. You can call them 'agreed on' ;-) TITL insulin CELL 0.82657 78.580 78.580 78.580 90.00 90.00 90.00 ZERR 24 0.079 0.079 0.079 0.00 0.00 0.00 LATT -1 SFAC C H N O S P Mg Pt UNIT 6144 13248 1560 3336 144 0 0 0 MORE 3 HKLF4 END I did not check how much you could reduce further before shelxl stops printing the radii.

Hi -
I'm writing a Python script to measure the volume of pockets within protein structures - plus extra bells and whistles... thus a custom job.
I was wondering just for speed, if someone could point me to values for van der Waals radii that are somewhat agreed upon for protein atoms, or if there is some dictionary already made that someone could point to that resides in phenix or some other structural biology package that would be ok for me to copy/use.
Thanks,
Dave
