Hi, 

I ran split libraries on my fastq file with 

split_libraries_fastq.py -i 'Read2.fastq' -o 'Read2' -b 'barcodes.fastq' --store_qual_scores --barcode_type 8 --store_demultiplexed_fastq -q 19 -m '/home/lauren/Desktop/61717_MiSeq/Task3Mappingrevc8bc.txt' 

and got the following error

Traceback (most recent call last):
  File "/home/lauren/qiime_software/qiime-1.8.0-release/bin/split_libraries_fastq.py", line 360, in <module>
    main()

    yield record[0][1:], record[1], record[3]
IndexError: list index out of range

I thought that perhaps this was an error caused by mismatched labels somewhere, so I ran compare_fastq_labels.py (https://gist.github.com/walterst/5397234 ) but found nothing. 

I attached my mapping file to this post.

The first ten lines of Read2 and barcodes.fastq are as follows

USEARCH is not freely redistributable and is thus not included in the
default QIIME package.
You may obtain a personal copy of the 32-bit program at no charge.

To use this feature, please go to:

Download USEARCH v5.2.236, then:
    sudo mv usearch* /usr/local/bin/usearch
    sudo chmod a+x /usr/local/bin/usearch

You probably also want to install USEARCH 6.1 as /usr/local/bin/usearch61

This data was generated by an Illumina MiSeq.  I appreciate any help with this troubleshooting adventure!

Best,
Lauren

Found the culprit! The last lines in the file had some sequence information without matching quality information.  I used tail -n -# to create versions of the fastq files without the last lines belonging to the problem read at the end of each file, then tried split_libraries_fastq.py again and it worked!
