Group - the electrode group.

Cluster - the cluster ID

Structure - the brain structure where the unit was recorded.

Type - the type of neuron, e.g. pyramidal cell.

I.D. - the isolation distance, which provides a quantitative measure of isolation quality.

Quality - a qualitative measure of isolation quality, which can be used to compare across different recording systems (isolation distances cannot be compared between e.g. a tetrode and an octrode).

Notes - user comments, e.g. about unresolved similarity between clusters.
