[gmx-developers] problem with the reverse transformation coarse grained to all atom

[francesca vitalini]

Dear all,
I'm trying to make a reverse transformation from cg to aa work, so I
started from a toy system. Took the pdb and converted in topology, run
the ./martinize.py script and obtained a cg.top cg.gro and cg.pdb.
Unfortunately, when I try the reverse transformation I encunter the
following error:
Number of fg atoms 25
Number of cg atoms 5
Reading frames from gro file 'MODEL        1', -1 atoms.
-------------------------------------------------------
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 Need Love, Not Games" (Iggy Pop & Kate Pierson)
: Cannot allocate memory

Any idea what it means?
thanks
