Re: [AMBER] Ambertools1.5, mmpbsa.py. PB Bomb in pb_atmlist(): maxnba too short

Dear all,

I found this in the pb_list.f:

if (eclose + pclose + sclose + nclose + cntr > maxnba) then

         write(6, '(4x,a,i8)') 'PB Bomb in pb_atmlist(): maxnba too short'

However, I do not quite understand what the meanings of eclose, pclose,
sclose, nclose, cntr and maxnba are.

Could you please help me with this? I think understanding the meanings of
these terms could help me to solve my problem.

Many thanks!

Qiong
