neuprint_connection_table() and neuprint_simple_connectivity() return different partner sets.

[AsaBarthMaron]

I get different sets of connected partners when I query a bodyid using these two fns, but can't figure out why. E.g., neuprint_connection_table(1547454812) returns 647 partners neuprint_simple_connectivity(1547454812) returns 1146 partners

This is because by default neuprint_connection_table only returns objects that have been identified as "neurons", whereas neuprint_simple_connectivity returns everything -- including small unidentified fragments. In neuprint_connection_table you'd get the same results by using the parameter all_segments=TRUE.

Gotcha, thanks!
