Try to use the following:
x2top -f SiO2.pdb -o SiO2.top -name SIO2 -ff oplsaa -pbc
The -pbc option (in version 4.0.x) causes the program to hang. You have to use
-nopbc, even if the molecule is "infinite." You'll have to fix the topology
later. To use OPLS, the .n2t file will have to be modified to include the
appropriate Si-O connectivities which are not present by default.
