Hi
When i subjected the complex to EM, it gave following warning:
"1-4 interaction between 3063 and 3068 at distance 1.436 which is larger than
the 1-4 table size 1.000 nm. These are ignored for the rest of the simulation.
This usually means your system is exploding,"
These atoms are oxygens of 2 phosphate grps ofATP. Later if i continue, with SD
it converges with less precision. so i applied CG. It converged. But when I
carry out position-restrained dynamics, it gave # of LINCS warnings in both
cases. Does this mean EM is not done properly ? How should I address this ?
Regards,
Nikhil

Like I implied several emails ago, you should order the [molecules] entries
according to the coordinate file, as normal.
