I apologize for this issue — I think the recommendations in README.md
may be based on outdated information for both of these datasets. Could you try:
split_libraries_fastq.py -i mock-forward-read.fastq.gz -o split_libraries -m sample-metadata.tsv -b mock-index-read.fastq.gz --rev_comp_mapping_barcodes
and see if that does the trick?
Thanks for your quick response! For mock-5, I get the following:
mock-5$ split_libraries_fastq.py -i mock-forward-read.fastq.gz -o split_libraries -m sample-metadata.tsv -b mock-index-read.corrected.fastq.gz --rev_comp_mapping_barcodes
Traceback (most recent call last):

qiime.split_libraries_fastq.FastqParseError: Headers of barcode and read do not match. Can't continue. Confirm that the barcode fastq and read fastq that you are passing match one another.
This issue is my fault — I recently uploaded the fixed files per the recommendation in README.md
and forgot to remove this note. The unmodified files (mock-index-read.fastq.gz
) should work without error.
I have been making a number of fixes to data files recently and am currently working on a few updates, including to README.md
files, so I apologize if you run into any more issues — just let me know and I will fix asap. Thanks!
That worked! ..for mock-5. To be honest, I'm looking for a working set, so I can stick with mock-3-5. But for the purposes of furthering your project:
mock-7$ split_libraries_fastq.py -i mock-forward-read.fastq -o split_libraries -m sample-metadata.edit.tsv -b mock-index-read.fastq --rev_comp_mapping_barcodes

Thanks so much for your help!
Thanks for confirming! And thanks for the error report on mock-7.
Please let me know if you run into any additional issues.
@nbokulich, can this issue be closed now?
@gregcaporaso I am waiting for PR #58 to merge, which includes related edits to READMEs. Thanks!
The README files have been updated with #58. Thanks @fwhelan for catching this!
This must be an issue specific to me since no one else seems to have run into anything similar here. I don't have much experience with golay barcodes, so please mind my ignorance!
I have downloaded mock-5 and corrected the barcode headers as recommended in
README.md
. When I run split libs, I run into the following error:Similarly, I run into this error with mock-7:
I'm running Qiime 1.9.1 on Ubutnu 14.04.
Could anyone advice as to what I'm missing? Thank you!
