You are right to be leery of having large empty spaces, but "instabilities"
should not lead to empty output files. Sander prints a lot of information
before even starting to do any calculations. So you will need to search
for why your output files are empty. Start from the inputs that worked for
minimization, and try to modify them in a minimal way, running (say) just
10 steps of dynamics with ntpr=1.
