How to make a hole at the center of the membrane instead of the origin (0,0)?

[John-zzh]

Hi Tsjerk,

I'm using insane script recently to build transmembrane protein systems. when I did this: insane \ -o CG_full_dimer_SOL_ions.gro -p topol.top \ -hole 8 -ring \ -d 0 -pbc rectangular -x 35 -y 35 -z 15 \ -sol W -salt 0.15 \ -f CG_full_dimer.pdb \ -l DOPC:8 -l DOPE:1 -l DOPS:1 \ -dm 0.5

it just dig a hole across teh pbc, directly at the (0,0) of the XY plane. Is there anyway to dig a hole at the center of the membrane?
