This is really related to this question (Creating paper on software tool).
But there was this comment there which asked for more details about the software's domain.
I created (still in beta stage) a software for Brain Tumor, but I would like to publish (if possible) about the software itself and not so much on the validation of it. (This would be eventually a later paper).
What's is the best approach for publishing about this software "proposal" for usage in medical clinics?
My concern is that while it's being tested. It wasn't tested enough for a full paper, but I still want to publish it.
