Overlaying traces from simple neurite tracer to an other image (had to register it using SIFT because it was disaligned)

One of my images skewed when imaging it and so the end image I have has shifted. I’ve used SIFT to register it together. Previously, I had traced quite a lot of it using SNT but every time I open it, it opens on to the unaligned image. When I open traces with the aligned version open, I get the image below (see traces on top left corner).

Does anyone know if there’s a way to open the traces over the shifted image?

Thank you,


Welcome to the forum @MimiB!

The simplest way would be to export your tracings as SWC, then re-import using “File> Load Traces/(e)SWC…”, selecting the “Apply offset to SWC file co-ordinates” option and specifying the X, Y and Z offsets.
Alternatively, one would have to write a small script that applies the offsets to all the coordinates of the traced paths.
