All files are 20 x 20 μm (x,y) in every 50μm z spacing. 
All files are registered to the Allen CCF that you can find in the “Reference_Brains” folder. 

1. Anterograde_prejectome
In this folder, you will see two files. 
- max_PVH_last_clean.nii: Max projection data from 6 different dataset in different subregions of the PVH
- max_SO.nii: Max projection data from 4 different dataset in different subregions of the SO
The value represent in each voxel represent number of signal pixels in 400 (20x20 in x, y) pixel. 
For example, if the voxel value is 100, that means 25% (100/400) of the voxel is occupied with signals. 

2. OTR_mapping: OTR-density_mapping.nii
This is averaged density of 10 different samples from adult OTR-Venus reporter mice. 
Value in each voxel represent number of OTR(+) cells in a given voxel. 

3. Rabies_monosynaptic_input
- Rabies_Input_PVH.nii: Max projection data from 6 different monosynaptic input dataset in different subregions of the PVH
- Rabies_Input_SO.nii: Max projection data from 4 different monosynaptic input dataset in different subregions of the SO
