well, super-basic stuff… i can’t seem to get tools to work, at all…clearly something basic missing; i tried a little tutorial, which included a data set to download in a tar.gz format…this seemed to open into three views, but there is an instruction to set threshold values 410 to 4096, but what appe…

It sounds like you may have missed a step. Make sure you are using a tutorial from a recent version of Slicer. If you are still having trouble post some screenshots and someone should be able to make some suggestions for you.

it seems like i miss a step, no matter what i try… part of the problem, and I’ve done it myself, is that the people with the experince, and the spirit to contribute, have too much expertise, and simply can’t see the little things that they do, as second nature, and the preferences already set, and, …

It may be easier to post a full screenshot of your computer and mark where you don’t see what you expect. If you encounter any problems, you can try to use sample data sets, to see if there may be something special/unexpected in your data.

Here’s the ‘state’ I was in, using scissors tool, and the tools seem to be displaying, but not doing anything…you can probably spot in ten seconds what’s wrong… [Screenshot 2022-11-29 at 0.13.54 .png]

Thank you, the screenshot is very helpful! “Erase inside” erases parts from existing segments. You will not see any effect of this until you paint something. Choose “Fill inside” to paint something first (or use any of the other effects Paint, Draw, Threshold, etc.). I would also recommend to hide…

thanks, Maestro! perhaps you can imagine that this aspect of the erase and scissors tools are not at all self-evident? It seemed, to my simple mind, that one might simply use those tools to increase rendering performance by reducing image volume, or eliminate parts of the image that occlude other p…

[image] Lohi: i guess that what i was trying to do is more like a free-form ROI selection? You can use the scissors as the free-hand selection tool. Just change the mode from erase to fill as @lassoan suggested.

so…set scissors to “erase outside”…‘fill inside’…so, using scissors in the opposite way that one ‘intuitively’ expects. is it so that the scissors tool, used that way, affects all slices in a view, or sequence? learning a new tool set, while struggling with neurological problems is a bit of a hard r…

gee…“instead of thinking how it should be working”… i am working on getting a handle on it, but also comparing to the majority of applications, even graphical, or spectrum analyzers. it just means shifting mental gears. different isn’t always better, but one has to work with what is.
