Dear All:
I've got a problem when performing an mm_pbsa calculation with nmode. My
system has 10080 atoms and in order to calculate the entropy I made the
following modifications to the mm_pbsa and nmode modules:
1) in file src/nmode/sizes2.h:
change " parameter (maxatom=8000)" to " parameter (maxatom=50000)"
2) in file src/mm_pbsa/molsurf.h:
change "#define MAXAT 10000" to "#define MAXAT 50000"
3) in file src/mm_pbsa/mm_pbsa_calceneent.pm
comment the "unlink $nmodeout;" so that I can get the nmode out file
4) in file src/mm_pbsa/mm_pbsa_createinput.pm:
add "print OUT " cut = 10.0, \n"; " after line 95
add "print OUT " cut = 10.0, ismem = 1,\n ";" after line 114
Then I get the error message of

 /home_soft/home/simm03/program_head/amber9/exe/nmode -O -i nmode_rec.in -o
nmode_rec.1.out -c sanmin_rec.1.restrt -p ../Inactive_eq.top not running
properly

    Then I checked the nmode out file, it reads:

I found other users who also have this problem might have the problems like
"ASSERTion 'ier ==0' failed in nmode.f at line 105" because of no adequate
memories. But I don't have this problem. BTW I can run the example 04 for
nmode in the Example folder successfully with the modified modules. Could
you please help me with this problem? Thanks in advance ~

 

Best wishes,

Yun Du
