Originally posted by mcnelson.phd View PostThe GA, HiSeq, and MiSeq can all give you those 27-36 bp reads, but most likely it's GA or early HiSeq data. You should be able to roughly tell what machine was used from the sequence ID in the fastq file. I can't say for sure that it was always like this, but all current fastq files from Illumina instruments incorporate the sequencer's serial number in the ID
To give an example, for files coming off our MiSeq the sequence IDs all begin with @Mxxxxx. The M indicates the instrument is a MiSeq, and the serial # is the xxxxx. HiSeqs are HWI if I'm remembering this off the top of my head correctly.

I was wondering about the read length of different illumina instruments like:
Illumina GAIIx read length of 150+150
Illumina HiSeq read length of 100+100

Cheers,
HiSeq runs can be of varying length. In general, SE/PE/Multiplex 50bp to 150bp (on the HiSeq 2500 variant) would be common lengths at this time.
It would be difficult to know for sure but the reads you describe (27-36) could possibly have come from a GAII or GAIIx, specially if they are not of a recent vintage.

Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...-
