kappa {format} {path}

This command allows APBS to read the ion-accessibility function mapped to a mesh. The inputs are maps of ion accessibility values which range between 0 and the build Debye-Hückel screening parameter; these values have units of Å^-2. In general, this command will read kappa-maps written by write commands in earlier APBS calculations.

NOTE: if you choose this option, you must also include a read diel statement.

Arguments for this command are:

format

The format of the kappa map. Acceptable values include:

dx

OpenDX format

gz

gzipped (zlib) compressed OpenDX format. Files can be read directly in compressed form.
