Qnifft is a new option for use instead of DelPhi with DOCK 3.6 It is a poisson boltzmann solver program from Kim Sharp [[1]]. It has been integrated into the DOCK Blaster and DOCK 3.6 toolchain. For now if you make use of it, please cite:

Using the new code

A compiled qnifft binary is in $DOCK_BASE/bin/Linux/qnifft22_193_pgf_32

Running qnifft requires setting your $DELDIR environment variable to $DOCK_BASE/src/qnifft

The default way to run qnifft is to copy the qnifft.parm file from $DELDIR and run it by calling

qnifft qnifft.parm

If you're using DOCK Blaster, you can make the new electrostatic grids by typing:

make grids/rec+sph.qnifft.phi

or if you want to use the full DOCK Blaster toolchain you can type

make autonew

Once you have
