Hi,
Thanks for your feedback!
First - have you successfully run through the test data? If not, that's a good starting place just to make sure everything is installed and so on.
Is a bit hard to diagnose that problem without more info. Do you mind sending me the output of "ls -l" on original_reads/ hashed_reads/ and cluster_vectors? That would make it easier for me to tell what's going on.

Hi, Sorry for the delay and incomplete explanation. I attached the output from the ls -l commands for which you asked. I also attached the error files for each step, which were run multiple times and dumped into the same file. Sorry for the messy files; I included them for reference, just in case. Your code works well on the test data. I've tried LSA on two datasets that I have from freshwater lake metagenomes. One dataset has four metagenome samples, the other six: both are time series. One sample in each time series has a full lane of Illumina HiSeq 3000 data, which is more than 100 GB and the other samples are 10-20 GB each. I am able to get both datasets to the KmerCorpus step when it complains about the matrices not being aligned (as shown above). Does any of this information help diagnose the problem?
I should also mention that I'm converting your LSF scripts to SGE scripts, so I've been tinkering with the create_jobs.py script and customizing the qsub options. That customized file (which is incomplete, since I still haven't run through a complete run on my data) is also attached (as setupDirs.txt and create_jobs.txt). Very nice programming, by the way; it's modular, easy to read, and quick to edit. Some fun tricks, too. I'm learning a lot from reading your code.
ls_-lh_cluster_vectors.txt ls_-lh_hashed_reads.txt ls_-lh_original_reads.txt
CombineFractions-Err.txt CombineFractions-Out.txt CreateHash-Err.txt CreateHash-Out.txt GlobalWeights-Err.txt GlobalWeights-Out.txt HashReads-Err.txt HashReads-Out.txt KmerCorpus-Err.txt KmerCorpus-Out.txt MergeHash-Err.txt MergeHash-Out.txt SplitInput-Err.txt SplitInput-Out.txt
It's still a bit hard to tell where the problem is.
It looks like you had some errors in the very first step (SplitInput). Are you sure this step ran correctly? This step splits all of your input data into chunks that will be worked on in the individual distributed tasks downstream, and it expects a certain formatting of the input file names (see relevant section of docs below).
If you think that that ran correctly (despite the errors), then the next thing I would ask is to see the output of "ls -l" for hashed_reads/ and cluster_vectors/
Splitting the input files
Begin by splitting the original reads (from many samples) into many small files:
$ bsub < LSFScripts/SplitInput_ArrayJob.q
The purpose of this is to create many small files that can each be operated on by a single task in a distributed environment. The size of many job arrays downstream from this point are set by the number of chunks created in this step. Note that this code assumes the files are named sampleid..fastq.1 and sampleid..fastq.2 for paired reads. If you used some other naming convention, this needs to be reflected in line 26 in array_merge.py:
WARNING
If your input files are significantly different from paired fastq files separated into 2 parts (.fastq.1 and .fastq.2) plus a singleton file (.single.fastq.1), then you will either need to modify these python files, or just take it upon yourself to split your files into chunks containing ~1million reads each, and named like: sample_id.fastq.xxx, where ”.xxx” is the chunk number (eg ‘.021’)

Hi, Brian,
Thanks for the feedback. Many of those complaints from the bash shell occur on all our jobs (our admin hasn't bothered to fix them because they're innocuous). I'm pretty sure the split reads step worked properly and I followed your - very well written - instructions carefully. I will try again from scratch then send you the ls -l on the output directories. Thanks very much for your time; it's probably nearly impossible to troubleshoot from across the continent, but I appreciate your help.
Brian, I was able to resolve this by carefully heeding your warning: "If you used some other naming convention, this needs to be reflected in line 26 in array_merge.py" Thanks very much for pointing out the error; not sure why I missed that error message before. I appreciate your time!
That's great! Sorry again for any of my slow responses.
Let me know if you run into any more issues.

No worries Brian, I did have the same issue as #7 . If you check over there, I posted all the relevant data I could find about the problem. Thanks again, man!
