SAP makes statistical assingment of an unknown DNA sequence to taxa represented by sequences in GenBank. Each assignment is associated with a posterior probility that serve as a confidence in the assignment.
SAP is available as a web service too at: services.birc.au.dk/sap.
SAP is now distributed as a Docker image allowing it to run on both Mac, Windows, and Linux. To use SAP in this way, you need to download and install Docker Desktop. Having done that, you run sap from the command line using this command on Mac/Linux:
docker run --rm -v $PWD:/code/sap kaspermunch/sap:latest [arguments]
and this one on Windows:
docker run --rm -v %CD%:/code/sap kaspermunch/sap:latest [arguments]
The first time you do this it will pull the image from DockerHub and run it. On subsequent runs it will run the cached image.
See the documentation for how to use sap on the command line.
Where it is not possible to install Docker, as is often the case on shared computing facilities, the image can be pulled using Singularity (you only need to do this once):
singularity pull sap docker://kaspermunch/sap:latest
Then just run the image as any other executable:
./sap [arguments]
You can find more documentation and detail on how to install and run SAP on the web service under Downloads.
