Experiment metadata

Good morning everyone,
I am using the Allensdk python package to analyse mouse connectivity data through the MouseConnectivityCache. When I retrieve an experiment using the function mcc.get_experiments(), I find among its metadata two different information: ‘structure id’ and ‘primary injection structure’, which often refer to different structures. I wanted to know what this two data meant, in particular I can’t undestrand the meaning of the first, as the other one is self explainatory.
best regards,


Hi Pietro,

“structure_id " is the actual primary injection structure and should be the metadata column that is used. You should ignore the information in the 'primary injection structure”.

Thank you,
