The entry in the Basis column below indicates how the stock center updated breakpoint sequence coordinates:
R5 flank = insertion flanking sequence aligned to release 5 genome assembly (per FlyBase or R. Hoskins, personal communication)
R3 author statement->R5 = Parks et al. release 3 sequence coordinate mapped forward to release 5
A single entry in Basis applies to both endpoints; two values indicate the basis of left and right endpoints, respectively.
Values based on R3 author statements should be treated as approximations.

Our complementation tests have shown that 10% of the stocks in the original Exelixis deletion collection did not carry the described deletion and that 77% of the stocks are deficient. The remaining 13% are unconfirmed.
