Dear Patrick,
All of the errors you are seeing are coming from test cases that make use of
Divcon. All the standard QMMM tests have passed (or differ only in the last
decimal place), however the crambin test case that uses divcon, rather than
sander's built in QM routines has failed with NANQ errors. 2pk4_stan is
another divcon test as is 2pk4. The Antechamber failures have come about
because this also calls divcon in order to calculate the AM1-BCC RESP
charges. Here divcon has failed and the errors have propogated through into
the parameter files produced by Antechamber.
The crambin_2 and amoeba_jac errors are innocuous.
Thus I suspect this is a compiler problem with miscompilation of the divcon
code. It could take a long time to track this down. A quicker alternative
maybe to turn off optimization for the divcon part of the code. This will
slow down antechamber but that probably won't cause too many problems. It
will also slow down QM/MM MD calculations that specifically use divcon (NOT
the default QMMM implementation) and it is probably unlikely that you will
want to run divcon QMMM MD so try the following:
edit $AMBERHOME/src/dcqtp/mod/Makefile
change line 122 from:
F90FLAGS = $(FOPTFLAGS) $(FREEFORMAT_FLAG) $(MODULEDIR)../../sander
to
F90FLAGS = $(FFLAGS) $(FREEFORMAT_FLAG) $(MODULEDIR)../../sander
Then I would suggest rebuilding everything from scratch just to be certain
that everything gets recompiled.
cd $AMBERHOME/src
make clean
make
Hopefully the test cases will then pass.
All the best
Ross
