Half good and some not good results in a research paper?
It's important to remember that a paper is supposed to make some kind of contribution. It's not merely a report on "things you did". So if you have some good results and some inconclusive results, what's the contribution ? As sr3u says, you need to work out what's going on and come up with some answers. It's entirely possible that you fail in this endeavour and end up with NO paper. That's not fun, but it's something that you must accept as a possibility.
