README for hca-bind APBS examples

The example input files in this directory calculate the binding of a small molecule (acetazolamide) to a medium-sized protein (human carbonic anhydrase).

The UHBD calculations where performed using a van der Waals surface definition for the dielectric coefficient. This is simulated in the APBS input files by setting srad to 0.0.

1 The discrepancy in values between versions 0.4.0 and 0.3.2 is most likely due to three factors:

2 The discrepancy in values between versions 0.5.1 and 0.5.0 is most likely due to the following factor(s):
