Hi, 

Any idea if there's a way to get the Instrument type (i.e. NextSeq, HiSeq, etc), from the instrument name field in the Fastq read header? - I've tried looking for a map of sorts in Illumina's documentation, but to no avail. 

Thanks,  
Illumina provided the following information regarding FCID mapping to instruments. The indicated characters are the last four of the nine-character FCID (excepting MiSeq). Please note that this is not comprehensive and there may be new additions in the future.

AAXX = Genome Analyzer   
BCXX = HiSeq v1.5  
ACXX = HiSeq High-Output v3  
ANXX = HiSeq High-Output v4  
ADXX = HiSeq RR v1  
AMXX, BCXX =HiSeq RR v2  
ALXX = HiSeqX  
BGXX, AGXX = High-Output NextSeq  
AFXX = Mid-Output NextSeq  
5 letter/number = MiSeq
