ok after further investigation I know exactly how this happens:
you click “c” to split/cut.
you click a segment for red (or blue it doesnt matter which colour goes 1st for this bug, whether you do red > blue or blue > red it’s the same thing). Immediately after that 1st segment click the seg ID 0 gets unselected automatically. Hereafter if you select blue (or red if its your 2nd colour) and submit all is fine. Upon completion of the split the segment ID 0 gets automatically reelected.
but if instead you click clear (w/o selecting the 2nd colour and submitting) and/or if you select the 2nd colour and then clear w/o submitting.
voila segment ID 0 does not get automatically reselected and you need to do it manually.
Possible solutions:
→ remove split being able to deselect and/or reselect that option, making it effectively able to change only manually. (idk what purpose it serves to even have it deselected in either split or merge considering ID-less segments cannot be split or merged into/from anything in the 1st place.)
or
→ remove the option entirely from being clickable by humans and remove it from split/merge as we cant do anything w/ unsegmented IDs since again we cant do anything with those, and just make it perma enabled in the background w/o us or split being able to enable/disable it.
i am getting a bug where both segments get deleted after splitting a segment ( not in segment list) when clicking on the segment again in 2d it come back as splitted.
when pasting this link neuroglancer a new tab it looks to work correctly for a short time but soon get the bug again.
i’ve noticed this bug as well (in banc as well as pyr) since a bit before KK’s comment here: [addon] Undelete (BANC) - #9 by Krzysztof_Kruk I think it has something to do w/ neuroglancer’s new version and whatever they changed in there.
I think, this one might’ve been the fault of the Undeleted script (as @Nseraf correctly suggested). I’ve just released a new version and now it’s should work fine.
Hi All, is this bug still happening?
We had some issues with data storage for some datasets on Friday afternoon. I believe it is fixed now as of yesterday. Please let us know!
Hi Nseraf,
Are you still having issues with the Segment 0 being shown or toggled during split?
We pushed a fix for it back in May though there was a minor lingering issue with custom color segments. However, there was an update done to neuroglancer recently (the tab coloring is the most obvious) so it could be that the bug was reintroduced during this update.
Let us know or send us a link/screenshot of the issue so we can forward it along to the devs.
Hi, its fixed in pyr and EW2, it persists in banc, id make a desktop capture vid but im on a ferry to krete (vacas atm and i barely have wifi lol, i can make 1 tmrw at some point.
