For more detailed instructions, please visit the user guide on our wiki.

Clone the AutoGVP repository

git clone git@github.com:diskin-lab-chop/AutoGVP.git

Docker set-up

Pull the docker image.

docker pull pgc-images.sbgenomics.com/diskin-lab/autogvp:v1.0.1

Navigate to the AutoGVP root directory
```
cd AutoGVP
```

Start a docker image. Replace with any name and run the commands below:

docker run --platform linux/amd64 --name <CONTAINER_NAME> -d -v $PWD:/home/rstudio/AutoGVP pgc-images.sbgenomics.com/diskin-lab/autogvp:v1.0.1
docker exec -ti <CONTAINER_NAME> bash

Navigate to AutoGVP directory within the docker image
```
cd /home/rstudio/AutoGVP
```
Run AutoGVP (see example commands below).

Dependencies

VEP (v104)
InterVar
ANNOVAR
AutoPVS1 (v2.0)
bcftools (v1.17)

How to Run AutoGVP

AutoGVP Requirements (recommended to place all in the data/ folder):

VEP-annotated VCF file (*VEP.vcf) or VEP- and ClinVar-annotated VCF file (CAVATICA workflow only). For CAVATICA workflow, AutoGVP will use ClinVar annotation from sample VCF when external ClinVar VCF file is not provided.
ANNOVAR multianno file (*hg38_multianno.txt)
InterVar file (*intervar.hg38_multianno.txt.intervar)
AutoPVS1 file (*autopvs1.txt)
Variant submissions file (ClinVar-selected-submissions.tsv generated by select-clinVar-submissions.R)
ClinVar VCF (clinvar_yyyymmdd.vcf.gz optional user input or clinvar.vcf.gz will be downloaded with download_db_files.sh). This is an optional input for CAVATICA workflow; if not provided, AutoGVP will expect ClinVar annotation in VEP-annotated sample VCF (see above).

Custom workflow example run

Prepare input files by running VEP, ANNOVAR, InterVar, and AutoPVS1.
Download database files:
```
bash scripts/download_db_files.sh
```
Run select-clinVar-submissions.R. To customize conflicting interpretation resolution, users can provide a ClinGen Concept ID list to filter submissions against (--conceptID_list). When a list is provided, users can also determine how unsettled conflicts are resolved with the --conflict_res argument ("latest" or "most_severe"). For more details, see the FAQ. Example command:
```
Rscript scripts/select-clinVar-submissions.R --variant_summary data/variant_summary.txt.gz --submission_summary data/submission_summary.txt.gz --outdir results --conceptID_list data/clinvar_cpg_concept_ids.txt --conflict_res "latest"
```

Run AutoGVP; if output of scripts/select-clinVar-submissions.R is not provided, the script will be run prior to starting pathogenicity assessment

bash run_autogvp.sh --workflow="custom" \
--vcf=data/test_VEP.vcf \
--filter_criteria=<filter criteria>
--clinvar=data/clinvar.vcf.gz \
--intervar=data/test_VEP.hg38_multianno.txt.intervar \
--multianno=data/test_VEP.vcf.hg38_multianno.txt \
--autopvs1=data/test_autopvs1.txt \
--outdir=results \
--out="test_custom" \
--selected_clinvar_submissions=results/ClinVar-selected-submissions.tsv \
--variant_summary=data/variant_summary.txt.gz \
--submission_summary=data/submission_summary.txt.gz \
--conceptIDs=data/clinvar_cpg_concept_ids.txt \
--conflict_res="latest"

CAVATICA workflow example run

Download database files:
```
bash scripts/download_db_files.sh
```

Run select-clinVar-submissions.R (See custom workflow step 2 for optional conflict resolution parameters). For more details, see the FAQ. Example command:

Rscript scripts/select-clinVar-submissions.R --variant_summary data/variant_summary.txt.gz --submission_summary data/submission_summary.txt.gz --outdir results --conceptID_list data/clinvar_cpg_concept_ids.txt --conflict_res "latest"

Run AutoGVP; if output of scripts/select-clinVar-submissions.R is not provided, the script will be run prior to starting pathogenicity assessment

bash run_autogvp.sh --workflow="cavatica" \
--vcf=data/test_pbta.single.vqsr.filtered.vep_105.vcf \
--filter_criteria=<filter criteria> \
--intervar=data/test_pbta.hg38_multianno.txt.intervar \
--multianno=data/test_pbta.hg38_multianno.txt \
--autopvs1=data/test_pbta.autopvs1.tsv \
--outdir=results \
--out="test_pbta" \
--selected_clinvar_submissions=results/ClinVar-selected-submissions.tsv \
--variant_summary=data/variant_summary.txt.gz \
--submission_summary=data/submission_summary.txt.gz \
--conceptIDs=data/clinvar_cpg_concept_ids.txt \
--conflict_res="latest"
