ERRORS when running velocyto: ERROR - This is an older version of cellranger, cannot check if the output are ready, make sure of this yourself! ERROR - Can not locate the barcodes.tsv file!

Good afternoon Velocyto team, I know many users run into this issue, but I could not fix it by what was offered in the community. I am running velocyto in conda environment recommended by 10X genomics. My Cell Ranger output directory consists of the following files:

**- analysis (untared and ungziped folder)

• filtered_feature_bc_matrix (untared and ungziped folder)
• barcodes.tsv (ungiziped)
• features.tsv
• filtered_feature_bc_matrix.h5
• molecule_info.h5
• possorted_genome_bam.bam
• raw_feature_bc_matrix.h5
• web_summary.html**

I am running the following command: velocyto run10x /home/agera4/RNAvelocityHCI003GM/outs /home/agera4/genes.gtf

This is the errors I am getting:

2023-03-24 15:01:38,904 - ERROR - This is an older version of cellranger, cannot check if the output are ready, make sure of this yourself 2023-03-24 15:01:38,905 - ERROR - Can not locate the barcodes.tsv file!

What should I do to fix it?

Hi AsyaTiho,

I had similar issue. I was using the data provided by 10x Genomics tutorial. https://www.10xgenomics.com/resources/analysis-guides/trajectory-analysis-using-10x-Genomics-single-cell-gene-expression-data Command: velocyto run10x /scratch/s167561/trajectory_analysis/ /scratch/s167561/reference/10X_references/refdata-gex-GRCh38-2020-A/genes/genes.gtf

Have you figured out how to fix it?

Thanks, Yan

From the tutorial you should run velocyto as follows:

repeat_masker="/path/to/grch38_rmsk.gtf"
reference_genes_gtf="/path/to/refdata-gex-GRCh38-2020-A/genes/genes.gtf"
input_10x="$1"
echo ${input_10x}
velocyto run10x -m "$repeat_masker" "$input_10x"  "$reference_genes_gtf"

Your input_10x should be pointing to directory where 10x dumps all of the files (outs and logs etc).

BC matrix will be read using the following lines. Because it checks the outs in that directory if you give the outs as it was suggested. It adds path/outs again which cannot find the output.

    bcmatches = glob.glob(os.path.join(samplefolder, os.path.normcase("outs/filtered_gene_bc_matrices/*/barcodes.tsv")))
    if len(bcmatches) == 0:
        bcmatches = glob.glob(os.path.join(samplefolder, os.path.normcase("outs/filtered_feature_bc_matrix/barcodes.tsv.gz")))
    if len(bcmatches) == 0:
        logging.error("Can not locate the barcodes.tsv file!")
    bcfile = bcmatches[0]

in your case this is /home/agera4/RNAvelocityHCI003GM
