[gmx-users] reverse transformation

[francesca vitalini]

Hi all!
I'm having some issues with the reverse transformation, so I decided
to start from a toy system, alias the 1UBQ present in the martini
tutorial. After running the ./martinize script., before any energy
minimization, I try to reverse the transformation and I encounter the
following error message.

Program g_fg2cg, VERSION 3.3.1
Source code file: smalloc.c, line: 113

Fatal error:
calloc for fr->x (nelem=-1, elsize=12, file confio.c, line 919)

I started everything from the 1UBQ.pdb from which I have deleted the
water, with ./martinize.py I obtain a cg.top and a cg.gro.
using the GROMACS 3.3.1 version of pdb2gmx I get the aa.top

Trying to reconvert from cg to aa I obtain the message pasted before.
Any ideas?
