Pipeline to generate Molecular Pixelation data with Pixelator (Pixelgen Technologies AB)
nf-core/pixelator is a bioinformatics best-practice analysis pipeline for analysis of Molecular Pixelation assays.
It takes a samplesheet as input and will process your data using
pixelator to produce final antibody counts.
- Build amplicon from input reads (
- Read QC and filtering, correctness of the pixel binding sequence sequences (
pixelator preqc | pixelator adapterqc)
- Assign a marker (barcode) to each read (
- Error correction, duplicate removal, compute read counts (
- Compute the components of the graph from the edge list in order to create putative cells (
- Call and annotate cells (
- Analyze the cells for polarization and colocalization (
- Report generation (
Warning Since Nextflow 23.07.0-edge, Nextflow no longer mounts the host’s home directory when using Apptainer or Singularity. This causes issues in some dependencies. As a workaround, you can revert to the old behavior by setting the environment variable
truein the machine from which you launch the pipeline.
First, prepare a samplesheet with your input data that looks as follows:
Each row represents a sample and gives the design, a panel file and the input fastq files.
Now, you can run the pipeline using:
Please provide pipeline parameters via the CLI or Nextflow
-params-file option. Custom config files including those
provided by the
-c Nextflow option can be used to provide any configuration except for parameters;
To see the results of an example test run with a full size dataset refer to the results tab on the nf-core website pipeline page. For more details about the output files and reports, please refer to the output documentation.
