I encountered a problem while trying to run NAMD 2.8 using Amber
forcefield. I created the prmtop and inpcrd files using AmberTools 1.2 and
used them to run NAMD.
However it failed with the error - ' FATAL ERROR: Failed to read AMBER
parm file! '
The end part of the output file is as follows:
Reading parm file (prp_3sod_11238.prmtop) ...
Command = zcat prp_3sod_11238.prmtop.Z
Filename.Z = prp_3sod_11238.prmtop.Z
Command = gzip -d -c prp_3sod_11238.prmtop.gz
Filename.gz = prp_3sod_11238.prmtop.gz
FATAL ERROR: Failed to read AMBER parm file!

I've read in the archive about a similar error, which suggested deleting
the sections under the flags 'SCEE_SCALE_FACTOR ' and 'SCNB_SCALE_FACTOR '
from the prmtop file.
I checked for the same, but my prmtop file doesn't contain these sections.
What could be the possible error? Could you help me?
