nef-4d.x <Options>

This is 'bin/nef-4d.x':  calculate Hodge numbers of nef-partitions

Options: -h        prints this information

-f or -

use as filter; otherwise parameters denote I/O files

-N

input is in N-lattice (default is M)

-H

gives full list of Hodge numbers

-Lv

prints L vector of Vertices (in N-lattice)

-Lp

prints L vector of Points (in N-lattice)

-p

prints only partitions, no Hodge numbers

-D

calculates also direct products

-P

calculates also projections

-t

full time info

-cCODIM

codimension (default = 2)

-Fcodim

fibrations up to codim (default = 2)

-y

prints poly/CWS in M lattice if it has nef-partitions

-S

information about #points calculated in S-Poly

-T

checks Serre-duality

-s

don't remove symmetric nef-partitions

-n

prints polytope only if it has nef-partitions

-v

prints vertices and #points of input polytope in one line; with -u, -l the output is limited by #points:

-uPOINTS

... upper limit of #points (default = POINT_Nmax)

-lPOINTS

... lower limit of #points (default = 0)

-m

starts with [d  w1 w2 ... wk d=d_1 d_2 (Minkowski sum)

-R

prints vertices of input if not reflexive

-V

prints vertices of N-lattice polytope

-Q

only direct products (up to lattice Quotient)

-gNUMBER

prints points of Gorenstein polytope in N-lattice

-dNUMBER

prints points of Gorenstein polytope in M-lattice
