Hi Ross,

The following link is your suggestion on how deal with the large systems containing more than 5000 atoms for the nmode calculations.

http://amber.ch.ic.ac.uk/archive/200501/0213.html

I am using IBM-AIX system. I tried several options for the complilations (including -big option). Even with the nmode compliled with

parameter (memdrv=500000000)
parameter (maxatom=7500)
parameter (maxint=500)
parameter (maxvec=500)

failed to run the program successfully. In IBM-AIX systems that I am using, we can define a large memory. For example for my calculation I define #.resources= ConsumableCpus(1) ConsumableMemory(20gb)

The following is the message.

Total memory required : 420479422 real words

Total memory required : 15920988 integer words

Maximum nonbond pairs 15559830
ASSERTion 'ier == 0' failed in nmode.f at line 105.

Could you help me on how to deal with this?

Thanks in advance,
