Can You mix indexed with un-indexed library on MiSeq run ?
 
Would it be possible to mix indexed (8nt index for 16 samples) with un-indexed library (eg Rohland et al 2012 trimmed adapters) to run on the same MiSeq run ? Would the unindexed reads endup in unrecognized bin/unaligned bin (less of a problem) or clusters would not be registered - the run would have to be set to a indexed mode, to read the indices (my guess).
Thanks in advance!

The unindexed library should end up in the undetermined file. However, that file will also contain a small percentage of other reads including mismatched indices and PhiX if you added any in. It may be better to re-queue the analysis a second time with the sample sheet containing all Ns to filter out all indexed reads, leaving only the unindexed library in the undetermined single file.

Thanks!
Trimomatic should be able to recover these ( I hope!).
