BRIO

BRain area Input Output: visualization tool based on the Allen Brain Atlas projection database. It outputs a 3d reconstruction (circle size represents connectivity strenght) and a histogram.

Requirements

Example:

Agranular insular area input

3d representation histogram

Agranular insular area (dorsal) output

3d representation histogram

General instructions

In both the get_input and get_output files you have to point to the location of template_volume_10um.npy, annotation_volume_10um_by_index.npy and structure_tree_safe_2017.csv (line 25 to 27)

To get output of region:

>> get_output(exp_id)

exp_id is the experiment ID (a numer like this one 485903475). Download of the data from the server might be quite slow (5 min), depends on your connection.

To get input of region:

do a target search here and then download the resulting CSV file. Import this file in Matlab workspace and name it input_table. Then type:

>> get_input(input_table)

Injection located inside the area of interest are deleted automatically


Input is normalized by injection volume. Projection_density (sum of detected projection pixels / sum of all pixels in voxel) was used to determine connectivity strenght.


Thanks to cortex-lab for providing such useful repositories for free!!!
