Hello Everyone,
I’ve a 3D volume like this.
For the suggestions offered here, I’m trying to use Scissors
option in Segment Editor
to extract a subvolume.
I used the circular option in “Scissors” tab to cut the segment. After obtaining the circular volume, I used the “islands” effect to retain the largest island. Using “Islands” effect on the whole volume worked fine, but I am not sure why memory issues (“bad_alloc”) occurs for this small volume.
Unable to allocate 705421132 elements of size 4 bytes.
Second try:
QXcbConnection: XCB error: 8 (BadMatch), sequence: 24430, resource id: 2622306, major code: 42 (SetInputFocus), minor code: 0 10 islands created (566 ignored) Unable to allocate 705421132 elements of size 1 bytes.

I’d like to ask for inputs on what can be done to overcome this error
