Re: [AMBER] AmberTools suppose program

Start with something simple, and grow your suppose run from there.

For example, start with 2 or 3 .pdbs only - and ensure that they have
the same topology. Or, input the same (identical) .pdb three times -
and you should get 0.0s out.

My point is that when I run into segfault problems with nab (and
"suppose" by extension), starting with a simple system, and growing from
there, is the most productive way to move forward.

Also, try a simpler match string than ":15-18,106-109:C*,N*,O*,P" and
build up from there.

I believe you can source-debug the code with
nab -g suppose.nab -o suppose
gdb ./suppose
set arg -fit ":15-18,106-109:C*,N*,O*,P" ./oldpdb/*.pdb
run


Then, when it crashes, you can use "bt" to possibly figure out where it
died - but I'd only get into that when you try the "start simple and
grow" approach first.
