Hi, thanks for developing the Allen Brain Atlas.
I am freshman using the projection function, and wondering if there is any quick method to calculate the connectivity or directly download the corresponding matrix.
I want to count all possible links from cortex towards hypothalamus. I understand that I could put “cortex” in “Filter Source Structure(s)” and “hypothalamus” (HY) in “Target Structure(s)”. And I found the result could be saved by clicking “Download as CSV”. However, the column does not contain the information of the sub-region of hypothalamus (Target Structure).
Here, in another way, I set the “Target Structure(s)” as “PVH” (a sub-region of PVZ in hypothalamus). I get two results as the attached figure. However, when I download the data, I found there were much more results in this csv file rather than 2 results shown in website. Could any one please tell me what I did wrong?
And my second question is that how could I download all the data containing (1) all projections from cortex towards hypothalamus, (2) the detailed note on the sub-regions of corresponding cortex and hypothalamus, and (3) the “Inj Site Vol” and “Tgt Vol” of the corresponding sub-regions.
Look forward to your early reply. Best wishes!
