Q:

I would like to calculate the solvent accessible surface of certain
proteins. By using your method (online available on
http://helixweb.nih.gov/structbio/basic.html) one can set the probe radius
to maximal size of 1.6 Å. Because I would like to mimic methylene groups as
solvent, the probe radius should be ~1.9 Å (Johnson R.M. et al, Biochemistry
2006, 45, 8507-8515) .
Is there a possibility to increase the probe size radius to 1.9 Å and
calculate the accessible surface using your method?
