Hi Team,

I have been trying to do the denoising of my data using the deblur. Following the tutorial ''[Alternative methods of read-joining in QIIME 2 — QIIME 2 2019.1.0 documentation](https://docs.qiime2.org/2019.1/tutorials/read-joining/)'', i have joined and filtered the paired end reads, but deblur denoise plugin is giving me the error below:

**Plugin error from deblur:**

Command '['deblur', 'workflow', '--seqs-fp', '/tmp/qiime2-archive-ppi4z3cm/01ce9654-3f1b-4288-a0cb-ec86f3b857ba/data', '--output-dir', '/tmp/tmpp0x7\_2p2', '--mean-error', '0.005', '--indel-prob', '0.01', '--indel-max', '3', '--trim-length', '435', '--left-trim-length', '0', '--min-reads', '10', '--min-size', '2', '--jobs-to-start', '1', '-w', '--keep-tmp-files']' returned non-zero exit status 1.

**Command used:**  
qiime deblur denoise-16S --i-demultiplexed-seqs home/qiime2/Desktop/demux-joined-filtered.qza --p-trim-length 435 --p-sample-stats --o-representative-sequences home/qiime2/Desktop/rep-seqs.qza --o-table home/qiime2/Desktop/table.qza --o-stats home/qiime2/Desktop/deblur-stats.qza

_The below information is for your reference:_  
**For trim length :** No matter what length I give, it throws similar error.

**This is the interactive plot information and overview of the demultiplexed filtered count:**

| Minimum: | 266 |
| --- | --- |
| Median: | 58303.5 |
| Mean: | 59164.08 |
| Maximum: | 83565 |
| Total: | 2958204 |

**These are the steps that I have done:**

**raw reads to demux input file with manifest file (prepared)**  
used input format PairedEndFastqManifestPhred33V2(as Phread64V2 gives error,)

**Joining Reads using vsearch**

**visualizing the summary of demux data**

**Sequence quality control**

**visualizing summary of filtered demux data**

Doubts:

Could this be possible as I have used raw data **assuming** that the primers and adaptors have already been removed from the reads? The files reads with extention: \*L001\_R001.fastq.gz. (as I don't have access to the indices used for the sequencing)

Hi @SciCatalyst,  
Could you please run this command with the `--verbose` flag to view the complete error message?

Thanks.

Dear Bokulich,  
Greetings.  
I would like to inform that the problem has been resolved.  
Actually I am running QIIME on Ubuntu in Oracle Virtual Box and was suggested that allocation of memory may be a problem, so just changed it and it worked. EUREKAAA!!!!!!!

Thank you.

Best,

Ojasvi
