Hi,

I'm trying to run one of the MD examples that come with the program, the one in /nwchem/examples/md/ache/mache.nw.
It returns an error, apparently in the prepare phase. Next are the last few lines of the output file.


Created restart mache_md.rst


Task  times  cpu:        5.3s     wall:        5.7s

Any idea why?

Thanks in advance

SOLVED!
Apparently it was a memory problem. I just set memory 1 gb (probably too much but just to be sure) and problem solved.

Dear all,
I have tried to run MD ( Tio2 example). For this work which I need .rst and .top files, generated by Prepare Task. For Prepare Task ,we should specify 7 files.(Tio2.nw ,Tio2.pdb ,Tio2.frg ,Tio2.seq ,Tio.sgm ,amber.par ).
After running Prepare Task, I have .rst and .top files. Then I have tried to run the MD task (for example dynamics) but I encountered with the following error:
EOF encountered on topology files

I appreciate any comment.
Thanks.
