Slab 27
This slab seems to have the most singularities
An example outside of neuropil
- In Gary's predictions ( 35261.0, 1747.0, 5933.0 )
- Equivalent point in raw data Saalfeld convention ( 35261.0, 112.0, 5933.0 )
- It's approximate location in the dvid export
Specific points
First note the points below are permuted YZ relative to the above. Second, the two source points below are displaced by 1 pixel in x, but are mapped to the same point.
- [35261.0, 5933.0, 112.0] -> [37764.3558499446, 9085.78999952591, 112.0]
- [35262.0, 5933.0, 112.0] -> [37764.3558499446, 9085.78999952591, 112.0]
This code produces the output:
p1 [35261.0, 5933.0, 112.0] -> [37764.3558499446, 9085.78999952591, 112.0]
p2 [35262.0, 5933.0, 112.0] -> [37764.3558499446, 9085.78999952591, 112.0]
source points are separated by: [1.0, 0.0, 0.0]
target points are separated by: [0.0, 0.0, 0.0]
