Select Your Data Type
Amplicon pipelines are used to identify bacterial or fungal communities based on specific genes. These workflows support both single-end and paired-end reads.
Requirements
Requirements
- Read type: Paired-end or single-end
- Min samples: 10 (for ASV/DADA2 workflows)
- File size: ≤ 1 GB uncompressed (250 MB compressed)
- PHRED score ≥ 20
-
Formats:
.fastq.gz
,.fq.gz
,.fasta.gz
,.sra.gz
-
Paired-end naming:
SampleID_R1_001.fastq.gz
SampleID_R2_001.fastq.gz
- Reads must overlap ≥ 15 bp
- Watch the 16S Tutorial Video
Workflow Options
Workflow Options
- ASV 16S rRNA Profiling (DADA2-based)
- OTU ITS rRNA Profiling (QIIME2-based)
Common Pitfals
Common Pitfals
- Filenames with spaces or special characters will break pairing
- Unpaired files will appear as “Single-read samples”
Uploading Metadata
You can upload a metadata CSV during or after your data upload through the Cohorts and Metadata page.
Workflow Selection
After upload, choose a workflow that matches your data type. The Cosmos-Hub will only show valid options based on your selections.
Do not close your browser while uploading. Progress is shown in the bottom-right. Allow up to 24 hours for processing. Results and statuses will appear in the Cohorts and Metadata section.
Occasionally a sample will fail to upload. Here are a number of possible causes:
- Poor internet connection
- Internet connection interruption
- Browser closed while uploading
- Incorrect primer pairs
- Corrupted or low quality data files
- If a sample fails to upload, you can retry it
- If a sample is not in the proper format or fails to run for another reason, the status will show “failed” and you will not be charged a credit.
- If you have problems uploading or with a failed sample, please submit a help ticket or email us at help@cosmos-hub.com.
