When I create the pdb file by ambpdb, I got the
following message?
ambpdb -p G.top < G.ann.x > g_md.pdb
| New format PARM file being parsed.
| Version = 1.000 Date = 09/18/07 Time = 23:12:25
At line 624 of file _ambpdb.f (Unit 5)
Traceback: not available, compile with -ftrace=frame
or -ftrace=full
Fortran runtime error: Bad value during floating point
read
Could you please give me some help for this ?
