1. Dilute non-diluted pool to 1 nM: Add 9.5 ul Pool 2 to 90.5 ul TE.

2. Dilute to loading concentration: Add 10 ul from above to 90 ul 10u 10uM Tris

3. Equilibrate FlowCell to RT ~10 minutes

4. Load 20ul onto iSeq cartridge

5. Start Run

Raw and parsed data are in: /project/microbiome/data/seq/Alfalfa/GBS/Alf1GBS_iSeq

cut -f 1,2 -d ',' Alf1GbsTest_Demux.csv | sed -E 's/(.*)/prepend,\1/' > Alf1GbsTest_Demux_simplified.csv 
sbatch parse_barcodes_slurm.sh   ## only took 86 minutes with the correct MID key
# to monitor number of samples recovered before the parsereport is complete
grep '@' parsed_AlfGbsTest_S1_L001_R1_001.fastq  | sed -E 's/@(.*) --.*/\1/' | sort | uniq | wc -l

At least one read was recovered from every one of the 764 MIDs that were used and in the Demux key.

Note that we need to preprocess the Demux key (line 1 above), to get it into form that the parser expects (three columns, with second column being the MID, and the third column being the sample name). For example, see below.
