Can an entire index be N padded in Miseq Reporter?

Yes, N's are considered wild cards in MiSeq Reporter (MSR). For example, an index can be assigned "NNNNNNNN".
This is useful in the following cases:
  1. 1.
    Index quality may be low and N padding can help reduce loss of index fidelity
  2. 2.
    A run was setup as dual index but single-indexed samples were included in the loaded library. In this case, MSR will not be able to detect barcode collision between the two sample types.
